WebbThe sampling theorem provides that a properly bandlimited continuous-time signal can be sampled and reconstructed from its samples without error, in principle. An early … WebbThe Nyquist-Shannon Sampling theorem is a fundamental one providing the condition on the sampling frequency of a band-width limited continuous-time signal in order to be able to reconstruct it perfectly from its discrete-time (sampled) version.
Webbresolution, nonuniform sampling, sampling theorems. I. INTRODUCTION THE sampling theorem is one of the most basic and fas-cinating topics in engineering sciences. The most well-known form is the uniform sampling theorem for bandlimited signals, due to Nyquist and Shannon [9], [13]. This has also been attributed to Whittaker and Cauchy (see [6]). Webb23 apr. 2008 · The Shannon’s equation relies on two important concepts: That, in principle, a trade-off between SNR and bandwidth is possible That, the information capacity depends on both SNR and bandwidth It is worth to mention two important works by eminent scientists prior to Shannon’s paper [1].
