![]() ![]() To avoid this problem, the sampling rate should be kept higher than twice the frequency of the input signal. In fact, it will become a different signal after reconstruction. If the sampling rate is very low then the resultant signal will not look anything like the original signal. This example shows that the sampling rate is 0.5 sec, as it takes 2 samples in one second. The sampling rate should be set according to the input signal. The number of samples taken during a single second is known as sampling rate or sampling frequency.
