Sampling is the rate at which an analog input signal is measured. For each sample, a
proportional binary number is generated. As you have seen, to preserve the content of
the analog signal for faithful reproduction the sampling rate has to be two or more times
the highest frequency content of the signal. Twice the highest frequency content is generally
referred to as the Nyquist rate.Sampling is the rate at which an analog input signal is measured. For each sample, a
