We now know enough to appreciate the fundamental rule concerning sampled monitoring of a periodic waveform: To digitize a waveform without aliasing, sampling must be at least TWICE the frequency of the waveform. As we already saw, even at twice the waveform frequency, there is a significant chance that we will underestimate ...
WebMay 31, 2024 · The Nyquist theorem is also known as the sampling theorem. It is the principle to accurately reproduce a pure sine wave measurement, or sample, rate, which must be at least twice its frequency. The Nyquist theorem underpins all analog-to-digital … WebThe 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.
