In signal processing, the Nyquist rate, named after Harry Nyquist, is a value equal to twice the highest frequency of a given function or signal. It has units of samples per unit time, conventionally expressed as samples per second, or hertz (Hz). [ 1 ]

Sep 12, 2024 · The theoretical minimal sampling rate at which a finite bandwidth signal can be sampled to retain all information and reconstructed from its sample without any distortion is called the Nyquist sampling rate (f n). The other term for the Nyquist rate is the minimum sampling rate.

Feb 27, 2024 · The Nyquist Sampling Theorem explains the relationship between the sample rate and the frequency of the measured signal. It is used to suggest that the sampling rate must be twice the highest frequency in the signal. It is used to reconstruct any signal from samples.

Nov 21, 2016 · If you sample a (real) signal $s(t)$ at $f_s>2B$ samples per second, then $s(t)$ can be reconstructed from its samples, where $B$ is the bandwidth of $s(t)$. The lower bound $2B$ is often called the Nyquist rate.

Jan 3, 2022 · Learn about the Nyquist Rate and Nyquist Interval, their significance in signal processing, and how they relate to data sampling.

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.

The Nyquist theorem defines the minimum sample rate for the highest frequency that you want to measure. The Nyquist rate is 2x the given frequency to be measured accurately. The theorem can be used in reverse.

Jan 28, 2020 · The Nyquist rate is the minimal frequency at which you can sample a signal without any undersampling. It's double the highest frequency in your continous-time signal. Whereas the Nyquist frequency is half of the sampling rate.

Apr 12, 2025 · 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., f_(Nyquist)=1/2nu.

Jun 17, 2020 · When the sampling rate becomes exactly equal to 2f m samples per second, then it is called Nyquist rate. Nyquist rate is also called the minimum sampling rate. It is given by, Similarly, maximum sampling interval is called Nyquist interval. It is given by, When the continuous-time band-limited signal is sampled at Nyquist rate (fs = 2f m), the ...
