Equipment that uses quantities represented as binary numbers. In a digital synthesizer every aspect of the sound generation is handled as a numeric calculation. The digital information is not audible and so must be converted to analog form by a DAC before it is output.
A signal that has only two levels per cycle [i.e., on or off (or 1 or 0)], as opposed to an analog signal, which can have an infinite number of levels per cycle. In telecommunications, digital signals offer superior sound quality over analog because there are only two levels to reproduce and any noise or interference introduced when the signal is transmitted is stripped out when the signal is regenerated.
In contrast to analog, digital representations consist of values measured at discrete intervals. Digital clocks go from one value to the next without displaying all intermediate values. Computers are digital machines employing a binary system, i.e., at their most basic level they can distinguish between just two values, 0 and 1 (off and on); there is no simple way to represent all the values in between, such as 0.25. All data that a computer processes must be digital, encoded as a series of zeroes and ones. Digital representations are approximations of analog events. They are useful because they are relatively easy to store and manipulate electronically.

As opposed to ANALOG. Digital electronics provides a way in which all information can be given a numerical value. This is done by using the fact that any connection can either be 'On" or "Off". By convention, "On" is considered to be the number 'One' and 'Off' is accepted as the number 'Zero'. This means that any combination of on and off can be viewed as a binary number e.g: 10110. Using binary mathematics therefore, exact values can be provided for all electrical phenomena. This precision makes digital technology very convenient and means that all systems using the concept can communicate since there is no ambiguity.

There are two main ways of doing things electronically, analog or digital. The digital method is to consider a circuit either on or off, a signal as either present or absent, with no levels in between. Electronic circuits using the digital mode are simple to design and non-critical in operation. The all-or-nothing nature of digital circuits make them immune to drift and distortion, and their simplicity makes them easy to manufacture in large quantity. Digitizing is defined as transforming a signal or piece of information into digital form.

Represented by a series of digits. Therefore not continuously variable but represented by steps. If the steps are sufficiently small then the human eye or ear cannot distinguish the digitally encoded information from an analogue equivalent. The advantage of digital representation is that images or sound can be recorded with absolute precision with error correcting codes. Such information is readily compatible with computers and digital processing.
A system or device in which discrete signals are used to represent continuous signals in the form of numbers or other characters. Information is represented by electrical "on / off", "high / low" or "1 / 0" pulses, instead of being represented by a continuously-varying quantity (e.g. signal voltage) as is the case in an Analogue system or device.
A digital signal is made up of a sequence of digital numbers. Digital numbers can only have certain, discrete values (compared with analogue signals which can range over a continuity of values). Analogue signals can be represented by digital ones, incurring quantisation noise (due to the difference between the nearest digital value and the actual analogue value). However, this usually is more than compensated for by more accurate transmission and reproduction, as digital signals suffer far less from noise and distortion effects
Digital information relies solely on Arabic numerals for expression. In computers, all information is processed in binary numerics (the numbers 0 and 1) through on/off electrical impulses.

The latest TV broadcast technology. To send a digital stream of information to your television set, a TV station takes tiny slices of the video image, assigns a numeric value to describe each slice, and mathematically encodes those values into equations. A traditional analog transmission, in contrast, has a more direct relationship to the pictures you watch. You could look at the television signals through an oscilloscope and see how the frequencies and voltage changes affect the sound, light, and color on your screen. In the audio world, this distinction means that if you hold an old vinyl record to the light, you might see small dark bands where the music grows louder and more dynamic.

Basically it refers to information in a discrete, rather than continuous (analog) form. Digital signals are virtually immune to noise, distortion, crosstalk, and other quality problems. In addition, digitally based equipment often offers advantages in cost, features, performance and reliability when compared to analog equipment. This process virtually eliminates generation loss as every digital-to-digital copy is theoretically an exact duplicate of the original allowing multi-generational dubs to be made without degradation.
Transmission and switching technologies employ a sequence of binary digits to convey information.
Electronic technology which is represented as a series of on/off impulses or electronic states (as opposed to wavelike transmissions such as radio and television).

Analog forms may be encoded for transmission on digital communications systems.
Any method of transmitting information through a binary system of zeros and ones. Morse code was an early form of digital communication (dots and dashes). Today, digital communication uses combinations of electrical signals (zero = off, one = on) to convey data.
A representation of data in a numerical form which consists of a discrete number of possible states. Modern computers and digital transmission systems, use the binary number system which has only two possible states, on and off, usually represented by the numbers 1 and 0 - a bit ( binary digit). Digital computers use codes consisting (usually) of 8 bits (a byte) to represent an individual character, such as a letter of the alphabet. Similarly, a digital system for storing or transmitting images will use codes to represent attributes of an image, such as colour and brightness. The numerical basis of the representation allows for sophisticated error-checking and processing which can lead to superior quality and greater capacity over any given transmission medium, such a phone line, than using an analogue representation.

The representation of information in a two state format, either “on” or “off,” 1 or 0. Computer programs, information, and instructions all exist in digital form. Speech, although an analog waveform, is often converted into a digital format for transmission or storage (such as in a voice mail system). The electrical transmission and switching of speech in digital form provides greater overall quality and less noise than doing so in analog form. Most modern switches are digital switches and represent improved quality over older analog switches.

discrete signals such as those represented by means of bits (which are either "on" or "off") as opposed to continuously variable analog signals. Used in both electronic and light- based systems, digital signals transmit audio, video, and data as bits. Digital technology allows communications signals to be compressed for more efficient transmission and provides for faster communication with easier error prevention than analog communi- cations. Computers process the bits in the form of bytes. About a half million bytes make a single still picture on a TV screen.
Digital is often banded about as a better alternative to Analogue. With a digital handset speech is sampled to create a binary series of ones and noughts which can be transmitted, and then decoded at the other end. The advantages of this to the network operator are immediate as more calls can be compressed into the same amount of free air space, but their are advantages to the user as well. As less data is flying, and the data can be corrected for errors, quality is improved, and additional services like caller id and text messaging can also tag onto the messages. Picture messaging is now starting to take off, and the next generation of digital mobile phones, known as 3G, should feature innovations like streaming video from one handset to another.

Of course, your computer is digital, and it needs a lot more information than just a one or a zero to keep it running. It uses digital information, made up of a complex series of ones and zeroes, to get the job done.[See Also: Analog

When copied, they do not degrade as an analog signal does. An analog-to-digital (A/D) converter chip takes samples of the signal at a fixed time interval known as sampling frequency. This digital stream is can be recorded onto magnetic media. Upon playback, a digital-to-analog (D/A) converter chip reads the binary data and reconstructs the original analog signal.

The use of binary code to represent information. There are two major benefits to digital signals: First, the signal can be reproduced precisely. This is especially helpful in long transmissions where the signal loses strength along the way, picking up static and other interference. Instead of just amplifying the signal (as is done in analog), the code is put through filter of sorts to delete the noise and then transmitted. The other benefit is that digital technology is becoming cheaper and more powerful, whereas analog is becoming a thing of the past.

Digital communications technology generally permits higher speeds of transmission with a lower error rate than can be achieved with analog technology. When analog signals are received and amplified at each repeater station, any noise is also amplified. A digital signal, however, is detected and regenerated (not amplified). Unlike amplification, any noise (less than a valid signal) is eliminated by digital regeneration.

The use of ones and zeros to represent physical information.
Technology where information is encoded before transmission.
Information encoded and expressed with the use of binary numbers representing many values in the real world. Digital information is distinguished by the fact that only predetermined values may be represented using zeros and ones. For example, a digital thermometer would display the temperature using pre-assigned values. On a digital thermometer, the temperature might read 76.2. The next higher reading available might be 76.3. The true temperature, however, could range anywhere between 76.2 and 76.3, such as 76.21, .22, .23 etc. The possible values existing between 76.2 and 76.3 are infinite, but the thermometer, limited by design, can only display pre-set values. Consequently, pinpointing exact values represented by digital data is virtually impossible. Though limited in this way, digital information has many advantages because extremely close approximations are easily achievable. Digital data is also easy to store and manipulate.

There are two main ways of doing things electronically, analog or digital. The digital method is to consider a circuit either on or off. A digital voltage or signal refers to the discrete nature of digital voltage potentials in digital circuits. TTL (Bipolar Transistor-Transistor Logic) defines 0.0 Volts as a logic 0 or low, and 5.0 Volts as a logic 1 or high; These are single values for clarity - there are actually ranges of voltage potentials around 0.0V and 5.0V which are recognized as low and high logic levels, respectively.
A method of representing data using binary numbers. An analog* signal is converted to digital by the use of an analog-to-digital (A/D) converter chip by taking samples of the signal at a fixed time interval (sampling frequency). Assigning a binary number to these samples, this digital stream is then recorded onto magnetic tape. Upon playback, a digital-to-analog (D/A) converter chip reads the binary data and reconstructs the original analog signal. This process virtually eliminates generation loss* as every digital-to-digital copy is theoretically an exact duplicate of the original allowing multi-generational dubs* to be made without degradation. In actuality of course, digital systems are not perfect and specialized hardware/software is used to correct all but the most severe data loss. Digital signals are virtually immune to noise, distortion, crosstalk, and other quality problems. In addition, digitally based equipment often offers advantages in cost, features, performance and reliability when compared to analog equipment.

A form of transmission that transforms analog signals – speech, for example – into a series of electrical or optical pulses that represent the binary digits 0 and 1. This numerical data is then converted into various forms depending on the type of network, such as electronic pulses for a wired network, optical light waves for fiber optics or radio waves for wireless transmission. Digital networks offer superior QoS, secure transmission and more bandwidth than analog lines.
An electronic signal system that depends on voltages that are turned on or off.These signal levels are always high or always low.Computers and associated technology use digital signals.Data in digital form may be copied many times with virtually no loss of quality or degradation because the data is not altered or distorted as it goes through the electronic system.

The alternative method for transmitting electrical signals to analogue. Binary bits characterize digital signals. A digital signal is either a binary 1 or 0, an on or off switch. There are no other digital values. The trend in modern electronics and communications is toward digital, since interference is not an issue unless it is large enough to change a signal from one extreme state to the other.

A digital system is one that uses numbers, especially binary numbers, for input, processing, transmission, storage, or display. Once media messages were in analogue form that could be distorted over long distances or when copied. Digital signals consist of on and off and do not distort.
Digital is the newer way of transmitting information. Instead of using sine waves and curves to send information, information is passed as simple 1's and 0's. (On and Off respectively) These long patterns of 1's and 0's actually represent information (sound and pictures) and need to be decoded once they are received.
The use of a binary code to represent information.
The use of binary code to record information. "Information" can be text in a binary code like ASCII, or scanned images in a bit mapped form, or sound in a sampled digital form, or video. Recording information digitally has many advantages over its analog counter part, mainly ease in manipulation and accuracy in transmission.
a signal in an electrical circuit that is limited to certain discrete values.
(1) In communications and computer technology, digital refers to a method of encoding information using a binary system made up of zeroes and ones. In communications technology this takes the form of two very different electrical voltages, several volts positive and negative, to represent the two values. This substantial difference in voltages for each state makes it unlikely that minor fluctuations in voltage due to electro-magnetic interference will change the way a signal is interpreted when received. (2) Information that is encoded into bits and bytes, or packets (0s and 1s, computer binary language). Generally perceived to be an advanced communication form offering clearer signals and increased transmission capacity.
A scheme for representing data via quantized, discrete steps. See analog.
A signal that consists of discrete states. A binary signal has only two states, 0 and 1. Antonym of analog.
Digital data is data that is either on or off, one or zero, high or low. A pushbutton is a good example of data that is represented digitally. The button is either pressed, or not pressed. The amount that the pushbutton is pressed is not measured. A pushbutton that is pressed half-way down is still considered to be "off" until it makes final contact with the microswitch beneath it, at which point it is considered "on." Compare to Analog.
An electrical signal converted into a form consisting purely of on-off pulses, similar to those found within computers. The nature of this transmission system eliminates most errors and distortion, providing a more reliable means of sending information.

Pertaining to a class of devices or circuits in which the output varies in discrete steps (i.e. pulses or "on-off" operation).
Pertaining to data in the form of digits. In signals, digital refers to a signal that assumes one of a predetermined set of values, such as 0 to 1, as opposed to a signal that may assume any value over a continuing range of values, such as an analog signal.
The process of representing and processing information that has been converted to binary numeric data. A digital image is made up of rows and columns of individual picture elements (pixels). In a full color RGB image each pixel is encoded as three 8 bit binary numbers which represent the brightness level each of the three colors (RGB). Because the entire image is recorded as a vast array of numbers it is possible for a computer to perform calculations on those numbers in order to manipulate the images.
A method for handling, storing and transmitting information based on the use of distinct electronic or optic pulses that represent the binary codes 0 and 1. Digital transmission techniques employ the sequences of these pulses to represent information, instead of infinite varied analogue signals. Digital technique offers a three-time improvement both in regards to rate and capacity as compared to the analogue technique. The result is a more cost efficient transmission of voice, video and data.

I don't know enough about the various methods used here to discuss them intelligently, except to say -- watch out. Many "artists" have started using the computer to manipulate a photo or painting, print it out, and call it an original print. It's not, it's a computer-manipulated copy. Fine if you like the results, but you shouldn't be paying more than a few bucks for it. (If this subject really interests you; the real issue here is, who is The Creator? The artist who uses a few Photoshop effects to manipulate the image? Or the clever folks at Adobe who wrote the image-manipulating software? Most professionals default towards the latter and do not consider such images to be "original art.")
