"In signal processing, the Nyquist frequency (or folding frequency), named after Harry Nyquist, is a characteristic of a sampler, which converts a continuous function or signal into a discrete sequence. For a given sampling rate (samples per second), the Nyquist frequency (cycles per second) is the frequency whose … See more In this example, fs is the sampling rate, and 0.5 cycle/sample × fs is the corresponding Nyquist frequency. The black dot plotted at 0.6 fs represents the amplitude and frequency of a sinusoidal function whose … See more Early uses of the term Nyquist frequency, such as those cited above, are all consistent with the definition presented in this article.

WebMay 25, 2012 · Due to "folding" described above (the Nyquist frequency is also commonly known as the "folding frequency"), it is physically impossible for frequencies above 500Hz to appear in the FFT; higher frequencies will "fold" back and appear as lower frequencies. Does the FFT only return the amplitude value without the frequency? WebMar 24, 2024 · The Nyquist frequency, also called the Nyquist limit, is the highest frequency that can be coded at a given sampling rate in order to be able to fully reconstruct the signal, i.e., See also Fourier Series, Fourier Transform, Nyquist Sampling, Oversampling , Sampling Theorem Explore with Wolfram Alpha More things to try: asymptotes of erf (x)
