In practice, because of the finite time available, a sample rate somewhat higher than this is necessary. A sample rate of 4 per cycle at oscilloscope bandwidth would be typical.

Webb1 Theory 1.1 The Nyquist-Shannon sampling theorem The Nyquist theorem describes how to sample a signal or waveform in such a way as to not lose information. Suppose that we have a bandlimited signal X(t). Bandlimited means that if we were to take the Fourier transform of this signal, X^(f) = FfX(t)g, there would be a certain f Webb19 okt. 2024 · The mathematical field of information theory attempts to mathematically describe the concept of “information”.

WebbSHANNON–HARTLEY THEOREM In information theory, the Shannon–Hartley theorem tells the maximum rate at which information can be transmitted over a communications channel of a specified bandwidth in the presence of noise.
