The Nyquist frequency, named after electronic engineer Harry Nyquist, is half of the sampling rate of a discrete signal processing system. It is sometimes known as the folding frequency of a sampling system. The Nyquist frequency should not be confused with the Nyquist rate, the latter is the minimum sampling rate that satisfies the Nyquist sampling criterion for a given signal or family of. The Nyquist-Shannon sampling theorem is a theorem in the field of digital signal processing which serves as a fundamental bridge between continuous-time signals and discrete-time signals.It establishes a sufficient condition for a sample rate that permits a discrete sequence of samples to capture all the information from a continuous-time signal of finite bandwidth

A TV signal with a bandwidth of 6 MHz is transmitted using PCM. The number of levels in the quantizer is 4096. Assume the sampling rate is 20% more than the Nyquist rate In elettronica e telecomunicazioni, il teorema del campionamento di Nyquist-Shannon o semplicemente teorema del campionamento, il cui nome si deve a Harry Nyquist e Claude Shannon, è un risultato di notevole rilevanza nell'ambito della teoria dei segnali.. Definisce la minima frequenza, detta frequenza di Nyquist (o anche cadenza di Nyquist), necessaria per campionare un segnale analogico. Nyquist Sampling Rate = The minimum sample rate that captures the essence of the analog information. Note that while Nyquist is appropriate for sampling, it may not capture nuances in information. But, of course, those nuances are higher frequency, and thus would require a higher Nyquist sample rate

In signal processing, undersampling or bandpass sampling is a technique where one samples a bandpass-filtered signal at a sample rate below its Nyquist rate (twice the upper cutoff frequency), but is still able to reconstruct the signal.. When one undersamples a bandpass signal, the samples are indistinguishable from the samples of a low-frequency alias of the high-frequency signal Signal & System: Nyquist Rate and Nyquist Interval in Sampling Theorem Topics discussed: 1. Nyquist Rate. 2. Nyquist Interval. 3. Calculation of Nyquist Rate..

For Nyquist theorem N samples are necessary to exactly reconstruct the power spectrum density. Compressed wideband spectrum sensing based on discrete cosine transform As you can see, sampling at 2 kHz accurately represents the frequency component according to the Nyquist Theorem , but sampling at 10 kHz better represents the shape of the original signal Given a noiseless channel with bandwidth B Hz., Nyquist stated that it can be used to carry atmost 2B signal changes (symbols) per second. The converse is also true, namely for achieving a signal transmission rate of 2B symbols per second over a channel, it is enough if the channel allows signals with frequencies upto B Hz In practice, an ADC's sampling rate should be much higher than twice the maximum signal frequency. A value of five times is a good choice. In most data acquisition systems, the analog input is filtered to eliminate any signal components above the Nyquist frequency. This is often referred to as an anti-aliasing filter Therefore the Nyquist rate for this signal is $ 6\pi $. --Cmcmican 23:11, 30 March 2011 (UTC) Instructor's comments.
