WebThe rate at which an ADC converts the continuous analog signal to digital data is called “Sampling Rate”. And if it takes Ts time to convert a single sample, then the sampling rate of this ADC is Fs = 1/Ts. Then the original analog signal can be reproduced from the discrete-time digital values by mathematical interpolation.
