What Is Analog-to-digital Conversion Of Signals? |
|
Answer» A DISCRETE-time SIGNAL is defined by specifying its VALUE only at discrete TIMES, called sampling INSTANTS. When the sampled values are quantised and encoded, a digital signal is obtained. A digital signal is obtained from the analog signal by using an analog-to-digital converter. This entire process is referred to as the conversion of signals from analog to digital form.
