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. Some later publications, including some respectable textbooks, call twice the signal bandwidth the Nyquist frequency; this is a … See more WebApr 2, 2024 · You are sampling three waves f 1 = 10 Hz, f 2 = 30 Hz, and f 3 = 70 Hz, with a sample frequency of F s = 1.5 × 70 Hz = 105 Hz. This means that your Nyquist frequency is F N = F s / 2 = 52.5 Hz, and corresponds to the maximum value of your frequency axis.
