A continuous wave transmission expressed by bandwidth, or range of frequencies. Telephones turn voice vibrations into electrical vibrations of the same shape. Analog implies continuous operation in contrast with digital, which is broken up into numbers. By converting analog signals into digital, the original audio data can be preserved.
A method of transmitting signals (voice, video, data) in which the transmitted signal is analogous to the original signal. In other words, if you spoke into a microphone and saw your voice on an oscilloscope and you took the same voice as it was transmitted on the phone line and threw that signal onto the oscilloscope, the two signals would look essentially the same. The only difference would be that the electrically transmitted signal would be at a higher frequency.
A type of transmission in which a continuously variable signal encodes an infinite number of values for the information being sent (compare with "digital").
An analog signal or transmission changes its amplitude infinitely over a given interval, whereas a digital signal shifts its amplitude only between discrete values (ex. between 0 and 1, "on" and "off" states, etc). Data used on PCs consists of digital signals. Analog signals have been used popularly due to their relatively simple structure. The structure of digital signals is more complex, but digital transmission is highly reliable since it utilizes only 0 and 1 signals and thus capable of withstanding noise and interference.
The traditional telephone technology (for voice transmission) in which sound waves (or other data) are converted into electrical impulses of varying strength or amplitude.
Transmission of a continuously variable signal as opposed to a discretely variable signal. Also called analog signaling.
an electromagnetic signal that varies continuously through time, taking on "values" that lie anywhere between the highest and lowest signal levels
In analog communications such as radio and television broadcasting throughout most of the 20th century, information is transmitted by modulating a continuously varying electronic signal such as a radio carrier wave.
In telephony, a method of conveying voice, data, image or video information by a signal that varies continuously in amplitude or frequency with the information being transmitted.
The traditional telephone technology in which sound waves or other information are converted into electrical impulses of varying strengths or amplitudes.
A signaling technology in which sound waves or other information are converted into electrical impulses of varying strengths. Analog transmission is the traditional telephone technology for voice transmission.
The broadcasting of a signal using an analog recording. Examples of use include radio.
Transmission of a continuously variable signal as opposed to a discrete on/off signal. Analog is the traditional way of transmitting a telephone or voice.
a way of sending signals—voice, video, data—in which the transmitted signal is analogous to the original signal.
The transmission of a continuously variable signal, as opposed to a discrete (digital) one.
Traditional telephone technology in which sound waves or other information are converted to electronic impulses of varying strengths. Most cable TV programming today is sent to customers’ homes in analog format.
Analog transmission is a method of conveying voice, data, image, signal or video information using a continuous signal which varies in amplitude, phase, or some other property in proportion to that of a variable.
