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.

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 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 …

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 …

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.

Dec 2, 2024 · One way to do this is to sample the analog signal at a minimum of twice the maximum frequency of the wave, as stated by the Nyquist Theorem. As long as we abide by this theorem, our …

Definition The Nyquist Rate is the minimum sampling rate required to accurately capture a signal's information without introducing aliasing, specifically defined as twice the highest frequency present in …

Jun 23, 2025 · Unravel the Nyquist Sampling Theorem: This article explores the fundamental concept in digital signal processing, detailing how it determines the minimum sampling rate required to avoid …

Aug 6, 2025 · Frequency Response and the Nyquist Stability Criterion Frequency response is a powerful method to analyze and design control systems based on how they react to sinusoidal inputs. Unlike …

In signal processing, the Nyquist rate, named after Harry Nyquist, is a value equal to twice the highest frequency (bandwidth) of a given function or signal. It has units of samples per unit time, …
