WebbThe sampling theorem states that, “a signal can be exactly reproduced if it is sampled at the rate f s, which is greater than or equal to twice the maximum frequency of the given signal W .”. Mathematically, we can write it as. f s ≥ 2 W. Where, f s is the sampling rate. W is the highest frequency of the given signal.
