Harry Nyquist, ursprungligen Harry Theodor Nyqvist, född 7 februari 1889 i Nilsby i Stora Kils socken, död 4 april 1976 i Harlingen, USA, var en svensk-amerikansk elektroingenjör och fysiker. Hans arbeten om signalöverföring bidrog till utvecklingen av informationsteorin .

A number of novel theoretical methods have been developed in an attempt to analyse data produced by sampling a signal at below the Nyquist rate and the limitations of the approaches have been investigated. A technique is developed that allows, under specified conditions, the frequency and amplitude of a band-limited sinusoidal signal (with no harmonics) to be determined when the signal is Shannon’s Sampling Theorem. Shannon’s Sampling theorem states that a digital waveform must be updated at least twice as fast as the bandwidth of the signal to be accurately generated. The same image that was used for the Nyquist example can be used to demonstrate Shannon’s Sampling theorem. Introduction. With the introduction of the concept of signal sampling, which produces a discrete time signal by selecting the values of the continuous time signal at evenly spaced points in time, it is now possible to discuss one of the most important results in signal processing, the Nyquist-Shannon sampling theorem. From the opposite point of view, the sampling rate must be greater than twice the highest frequency we wish to reproduce.* This frequency, half the sampling rate, is often called the Nyquist frequency.

Signal Sampling: Nyquist - Shannon Theorem. Theory. A continuous-time (or analog) signal can be stored in a digital computer, in the form of equidistant discrete points or samples.The higher the sampling rate (or sampling frequency, fS), the more accurate would be the stored information and the signal reconstruction from its samples.

Even today as we digitize analog signals, Nyquist's theorem is used to get the job done. Here’s to the science that keeps us connected. Shannon’s Sampling Theorem. Shannon’s Sampling theorem states that a digital waveform must be updated at least twice as fast as the bandwidth of the signal to be accurately generated. The same image that was used for the Nyquist example can be used to demonstrate Shannon’s Sampling theorem.

This book covers the basics of digital signal processing (DSP) for acoustic wave fields. It discusses familiar tools, such as the Nyquist sampling theorem, the

It ma y be stated simply as follo ws: The sampling fr e quency should b at le ast twic the highest fr e quency c ontaine d in the signal. Or in mathematical terms: f s 2 c (1) where f s is the sampling Nyquist theorem says that to represent frequency Fn, you need at least twice as much sampling rate Fs=2*Fn - this is a minimum and in practice we like to sample much more (though we try to keep it reasonable on the other side, each time you double the sampling rate, you add to computation time and file storage burden). Nyquist Theorem -- Sampling Rate Versus Bandwidth 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 high-frequency content will alias at a frequency inside the spectrum of interest (passband). Nyquist's sampling theorem, or more precisely the Nyquist-Shannon theorem, it is a fundamental theoretical principle that governs the design of mixed signal electronic systems. Modern technology as we know it would not exist without analog to digital conversion and digital to analog conversion. Een voorbeeld van deze vouwvervorming is weergegeven in Figuur 1, waar f s de sampling-snelheid voorstelt en 0,5 f s de Nyquist frequentie is die daarmee overeenstemt.
