Shannon’s sampling theorem
Webb23 aug. 2016 · The sampling theorem or Nyquist-Shannon theorem This post deals with one of the fundamental theorem of signal processing: the sampling theorem or Nyquist-Shannon theorem (have a look on wikipedia ). Webb18 juli 2024 · Nyquist Theorem. The Nyquist theorem states that an analog signal must be sampled at least twice as fast as the bandwidth of the signal to accurately reconstruct the waveform; otherwise, the high-frequency content creates an alias at a frequency inside the spectrum of interest (passband). An alias is a false lower frequency component that ...
