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, conventionally expressed as samples per second, or hertz (Hz). [1] When the signal is sampled at a higher sample rate (see § Critical frequency ...
6 de abr. de 2020 · Harry Nyquist was born in Nilsby, Sweden on February 7, 1889, according to an encyclopedia entry on his life. Nyquist was an able student, but his family could not afford the cost of education beyond the basics. So, at fourteen, he set to work in construction, saved his money, and a few years later, moved to the United States.
La frecuencia de Nyquist, llamada así por el ingeniero informático Harry Nyquist, es la mitad de la tasa de muestreo de un sistema de procesamiento de una señal discreta. También se le conoce como la frecuencia plegable de un sistema de muestreo. En la imagen utilizada abajo, se ve un ejemplo de como se pliegan los muestreos, donde fs es la ...
4 de ene. de 2022 · Harry Nyquist was a Swedish physicist and electronic engineer who conducted R&D at AT&T from 1917 to 1934. His research into reproducing sound signals, which was expanded upon by American mathematician and electrical engineer Claude Shannon, has come to be known as the Nyquist-Shannon sampling theorem.

Harry Nyquist (Nilsby (Zweden), 7 februari 1889 – Harlingen (Texas), 4 april 1976) was een Amerikaanse elektrotechnicus van Zweedse afkomst die van groot belang is geweest voor de ontwikkeling van de informatietheorie.Hij heeft belangrijk werk verricht op het terrein van onder andere thermische ruis en het digitaliseren van signalen (het bemonsteringstheorema van Nyquist-Shannon) (zie ook ADC).
The Nyquist–Shannon sampling theorem is an essential principle for digital signal processing linking the frequency range of a signal and the sample rate required to avoid a type of distortion called aliasing.The theorem states that the sample rate must be at least twice the bandwidth of the signal to avoid aliasing. In practice, it is used to select band-limiting filters to keep aliasing ...
