Synonym CAV.

A device that performs operations on data that are represented within the device by continuous variables having a physical resemblance to the quantities being represented.
Note: The earliest analog computers were constructed with purely mechanical components, such as levers, cogs, cams, discs, and gears. These components represented the quantities being manipulated or the operator-inserted values. Modern analog computers usually employ… (Read More →)

Data represented by a physical quantity that is considered to be continuously variable and has a magnitude directly proportional to the data or to a suitable function of the data.

The portion of the digital-to-analog conversion process that generates an analog signal value from the digital signal that resulted from analog encoding.
Note: Further action is required to integrate these samples to obtain a continuous approximation of the original signal, because analog decoding does not smooth the signal.

The portion of the analog-to-digital conversion process that samples an analog signal and creates a digital signal that represents the value of the sample.
Note: Multiple samples are needed to digitize a waveform over a time interval.
