WebbThe Sampling Theorem. Digital transmission of information and digital signal processing all require signals to first be "acquired" by a computer. One of the most amazing and useful results in electrical engineering is that signals can be converted from a function of time into a sequence of numbers without error: We can convert the numbers back ... 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.
