WebbShannon Sampling Theorem • If periodic x(t) is bandlimited to bandwidth and samples x[n] are obtained from x(t) by sampling at greater than Nyquist rate then can exactly reconstruct x(t) from samples using sinc interpolation formula • This is also called the cardinal series for x(t) Webbpossible and that Shannon’s sampling theory, in its modern and extended versions, can perfectly handle such “nonideal” situations. Ten to 15 years ago, the subject of sampling had reached what seemed to be a very mature state [26], [62]. The re-search in this area had become very mathematically oriented,

WebbThe Shannon theorem states the maximum data rate as follows: (5.2) where S is the signal power and N is the noise power. For example, if a system has bandwidth B = 3 kHz with 30-dB quality of transmission line, then the maximum data rate = 3000 log 2 (1 + 1000) = 29, 904 bps.

WebbOversampling. In signal processing, oversampling is the process of sampling a signal at a sampling frequency significantly higher than the Nyquist rate. Theoretically, a bandwidth-limited signal can be perfectly reconstructed if sampled at the Nyquist rate or above it. The Nyquist rate is defined as twice the bandwidth of the signal.
