Nyquist frequency - Wikipedia
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.
Nyquist Frequency -- from Wolfram MathWorld
Dec 3, 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.
Nyquist Sampling Theorem - GeeksforGeeks
Jul 23, 2025 · 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 …
What is the Nyquist Frequency & Does it Truly Matter? 2025
Mar 6, 2025 · The Nyquist frequency is one of the most important concepts in digital audio (whether you’re aware of it or not). It influences everything from sampling rate choices to avoiding aliasing …
What Is the Nyquist Theorem - MATLAB & Simulink - MathWorks
What Is the Nyquist Theorem? The Nyquist theorem, also known as the Nyquist–Shannon sampling theorem, defines the conditions under which a continuous-time signal can be sampled and perfectly …
Nyquist Theorem - an overview | ScienceDirect Topics
The Nyquist theorem is defined as the principle that the highest frequency that can be accurately represented in a sampled signal is half of the sampling rate. It specifies the minimum sampling rate …
Nyquist Frequency: Essential For Signal Sampling
Jan 13, 2025 · The Nyquist frequency is the maximum frequency at which a signal can be sampled without losing information. This frequency is named after Harry Nyquist, who first described it in 1928.
What is the Nyquist Theorem and Why is it Important
Dec 2, 2024 · The Nyquist-Shannon sampling theorem states that a CT signal should be sampled at a rate greater than twice the maximum component frequency (wM) present in the signal. This is the …
Simply stated, the Nyquist criterion requires that the sampling frequency be at least twice the highest frequency contained in the signal, or information about the signal will be lost.
Digital Audio Chapter Five: Nyquist Frequency
Following Claude Shannon's mathematical proof in 1948, it became known as the Nyquist Theorem or the Nyquist-Shannon Theorem. According to this theorem, the highest reproducible frequency of a …
