The first step in the process of converting an analogue signal into a digital representation. This is accomplished by measuring the value of the analogue signal at regular intervals called samples. These values are then encoded to provide a digital representation of the analogue signal

The process of converting an analog audio signal into digital form by taking periodic "snap-shots" of the audio signal at some regular interval. Each snapshot (sample) is assigned a number that represents the analog signal's amplitude at the moment the sample was taken.
The process of measuring the value of a signal at discrete points in time.
Taking sample values from a continuous analog stream at discrete intervals.
Converting analog information into a digital representation by measuring the value of the analog signal at regular intervals, called samples, and encoding these numerical values in digital form.
The process of converting an analog signal (such as a picture or a soundtrack) into digital form. In the case of a picture, a large number of small, evenly spaced areas are taken and each represented as one or more numbers for brightness (luminance) and color. These areas are referred to as picture elements or pixels. The more samples are taken, the more accurate (with higher resolution) an image can be reconstructed from the samples. For DVD, the image is 720 samples wide by 480 samples high for a total of 345,600 samples (may vary slightly). Even analog TV has sampling -- each scan line is a discrete (as in digital) sample in the vertical direction although it is continuous (analog) in the horizontal direction.
Sampling is process where the input signal is acquired at regular intervals.
the conversion of analog signals to discreet digital values through a preselected measurement process. SAR - see Specific Absorption Rate.
measurement at regular intervals of the amplitude of a varying waveform (in order to convert it to digital form)
The process by which analog signals are measured and converted into a digital number. Sampling occurs millions of times per second in order to convert analog video into digital video.
Part of the process of digital recording dissection of a signal in time, preparatory to quantization.
is the process of converting analog data to digital data by taking samples of the analog waveform at regular intervals.
taking the value of signal, usually as a voltage, and then, typically, digitizing it
The conversion of a continuous time analog signal into a discrete time signal.
Measurement at regular intervals of the amplitude of a varying waveform, so you can pick a point every so far to convert the waveform into digital.
Used to describe the regular, periodic measurement of a signal in order to digitise it. Sampling is usually done very frequently in order to ensure that rapid changes, such as those in a musical performance, are captured with sufficient detail.
The technique of recording a sound digitally (translating the analogue audio waveform into a series of electrical ons and offs that can be manipulated by a computer) for subsequent processing, editing and playback.
The process of converting a sound signal into numbers or 'samples'.
Consists of digitally recording acoustic, synthesized, or previously recorded sounds for the purpose of electronically manipulating them (e.g., changing pitch, changing timbre, looping them, etc.); in acid jazz, entire musical phrases from old albums are often sampled then resynthesized as the basis for new recordings.
The process of measuring the amplitude of an analog signal at regular intervals for the purpose of converting the signal into a digital format.
Sound is, by definition, an analog phenomenon because it occurs in continuous waves. To be used in a computer, it must be converted to a digital format. In order to do this, instruments measure, or sample, the frequency of the sound wave at specified intervals. That's known as the sampling rate. The higher the sampling rate, the more samples per second are taken by these instruments, and the truer the digital version will be to the original analog sound wave. However, the higher the sampling rate, the larger the resulting digital sound file will be -- because the number of samples being saved increases as well.
The process of digitizing analog information to identify relevant information.
A technique used to capture continuous phenomena, whereby periodic snapshots are taken. If the sampling rate is fast enough, the human sensory organs cannot discern the gaps between each snapshot when they are played back. This is the principle behind motion pictures. Sampling is the key technique used to digitize analog information. For example, music CDs are produced by sampling live sound at frequent intervals and then digitizing each sample. The term sampling is also used to describe a similar process in digital photography. Last Reviewed: 2003-04-22

The process of finding the instantaneous voltage of signal at a specific moment or repetitively at a given rate (the sampling rate).
Measuring the analog signal at a fixed rate of speed (sampling frequency).
the process of converting analog data into digital data by taking a series of samples or readings. Can also refer to the reduction of data by retaining only a portion of the original input set.
The process of converting analog data into digital data by taking a series of samples or readings at equal time intervals.
The method used to convert analog signals to digital form. Analog signals are sampled at some frequency in their digital conversion. For Sorenson Broadcaster this is used most commonly to determine the audio sampling frequency. A higher sampling frequency captures higher frequency audio.

digitizing a waveform by measuring its amplitude fluctuations at some precisely timed intervals. The accuracy of the measurements is a function of the bit resolution.
Digital process by which analog information is measured, often millions of times per second, in order to convert analog to digital.
Generally refers to the transferring of a slide, photograph, or other illustration from analog into digital form. For example, converting a photo into a scanned bitmap. Aliasing can be a result of sampling. In the example of scanning a photo to create a bitmap, the result might be jagged edges. This is fixed by anti-aliasing.
The process during which analog audio is converted into digital information. The sampling rate of an audio stream specifies the interval at which all samples are captured.
To record and play back a sound in waveforms on synthesizers or computerized instruments.
Sampling is part of analog to digital conversion. Essentially, the analog signal is sampled at an specific rate and quantized, which means a numerical value is matched to each sample, and that value is convened to binary code. Although the frequency of sampling is important for continuity, the size of the sample (in bits) is important for depth of quality.
The rapid measurement of a signal in its discrete time segments (see quantisation).
Measurement of an analogue signal (such as an audio or video signal) at regular intervals. The result of the measurement can be converted into a digital signal that can be electronically enhanced, edited or processed.
The conversion of a portion of an input signal into a number of discrete electrical values for the purpose of storage, processing and/or display by an oscilloscope. Two types: real-time sampling and equivalenttime sampling.
Converting analog signals into a digital format by measuring the analog signal’s value at regular intervals and encoding the numerical values in digital form.
The process of encoding an analog signal in digital form by reading (sampling) its level at precisely spaced intervals of time. See sample, sampling rate.
In music, sampling is the act of taking a portion, or sample, of one sound recording and reusing it as an instrument or element of a new recording. This is typically done with a sampler, which can be a piece of hardware or a computer program on a digital computer. Sampling is also possible with tape loops or with vinyl records on a phonograph.
In signal processing, sampling is the reduction of a continuous signal to a discrete signal. A common example is the conversion of a sound wave (a continuous-time signal) to a sequence of samples (a discrete-time signal).
