# 奈奎斯特頻率（英語： Nyquist frequency ）是離散訊號系統採樣頻率的一半，因瑞典裔美國工程師哈里·奈奎斯特（ Harry Nyquist ）或奈奎斯特－夏農取樣定理得名。

The Nyquist–Shannon sampling theorem tells us to choose a sampling rate fs at least equal to twice the bandwidth, i.e. fs=2B. The sampled signal is x(nT) for all values of integer n. In practice, a finite number of n is sufficient in this case since x(nT) is vanishingly small for large n. We chose n-nMax=10 for the maximum value of n.

What is the Nyquist Sampling Theorem? • Formal Definition: o If the frequency spectra of a function x(t) contains no frequencies higher than B hertz, x(t) is completely determined by giving its ordinates at a series of points spaced 1/(2B) seconds apart. • In other words, to be able to accurately reconstruct a The Nyquist–Shannon sampling theorem tells us to choose a sampling rate fs at least equal to twice the bandwidth, i.e. fs=2B. The sampled signal is x(nT) for all values of integer n. In practice, a finite number of n is sufficient in this case since x(nT) is vanishingly small for large n.

Och det är instängningssatsen. So what's the squeeze theorem? The Nyquist–Shannon sampling theorem provides a sufficient condition for the sampling and reconstruction of a band-limited signal. Samplingsteorin Nyquist av M Lundin — The Nyquist-Shannon Sampling Theorem.

### Nyquist's theorem: A theorem, developed by H. Nyquist, which states that an analog signal waveform may be uniquely reconstructed, without error, from samples taken at equal time intervals. The sampling rate must be equal to, or greater than, twice the highest frequency component in the analog signal. Synonym sampling theorem.

· sampling continuous signals to convert them to digital signals. · Nyquist sampling theorem showed that the the other hand, the Shannon–Nyquist sampling theorem, which dictates that channel capacity is preserved when the received signal is sampled at or above the Nyquist sampling theorem: understanding the illusion of a spinning wheel captured with a video camera. Luc Lévesque1. © 2014 IOP Publishing Ltd Physics The Nyquist theorem states that a signal must be sampled at least twice as fast as the bandwidth of the signal to accurately reconstruct the waveform; otherwise, The answer to this question is given by the Nyquist sampling theorem, which states that to well represent a signal, the sampling rate (or sampling frequency— not Nyquist, which states that an analog signal waveform may be uniquely reconstructed, without error, from samples taken at equal time intervals. The sampling rate The theorem proposed by Nyquist which states that an original analogue signal can be precisely recreated provided a specified minimum of samples are taken.

### The Nyquist Theorem is not specific to digitised signals (represented by discrete amplitude levels) but applies to any sampled signal (represented by discrete time values), not just sound.

fs=2B. The sampled signal is x(nT) for all values of integer n. In practice, a finite number of n is sufficient in this case since x(nT) is vanishingly small for large n. We chose n-nMax=10 for the maximum value of n. Sampling is a core aspect of analog-digital conversion.
