Sampling theorem in digital communication

WebSampling in statistics or research is defined as a method to select a subset from the large data. In digital communication, it is defined as a process of measuring the instantaneous value of an analog signal in the discrete form. Sampling is a process performed by a … WebThe sampling is thru in accord with the Sampling Theorem , i.e., the sampling frequency fs is kept equal to or higher than twice the maximum frequency W present in the input analog signal. If, however, fs<2W, then aliasing occurs, and recovery of the original analog signal …
