WebThis theorem states that the highest frequency which can be represented accurately is one half of the sampling rate. The Nyquist rate specifies the minimum sampling rate that fully describes a given signal; in other words a sampling rate that enables the signal's accurate reconstruction from the samples. Web• The solution: Shannon’s Sampling Theorem: A continuous-time signal x(t) with frequencies no higher than f max can be reconstructed exactly from its samples x[n] = x(nT s), if the samples are taken a rate f s = 1 / T s that is greater than 2 f max. • Note that the minimum sampling rate, 2 f max , is called the Nyquist rate.

"Webrequires sampling at greater than 4Kc to preserve and recover the waveform exactly. The consequences of sampling a signal at a rate below its highest frequency component results in a phenomenon known as aliasing. This concept results in a frequency mistakenly taking on the identity of an entirely different frequency when recovered. " - Sampling theorem in digital communication ppt
