With the advent of faster analog-to-digital converters (ADCs) and wide bandwidth sample and hold (S/H) circuits, it has become practicable to sample a bandpass signal directly without any demodulation …

WebDec 21, 2024 · Nyquist sampling means the opposite of sampling at the Nyquist limit. Nyquist sampling means sampling a higher frequency but bandwidth-limited signal but using aliasing at the Nyquist sampling rate to down-convert the signal to the baseband. What even is a "higher frequency" but "bandwidth limited" signal? WebTerm: Sampling rate (audio) Sampling rate or sampling frequency defines the number of samples per second (or per other unit) taken from a continuous signal to make a discrete or digital signal. For time-domain signals like the waveforms for sound (and other audio-visual content types), frequencies are measured in in hertz (Hz) or cycles per ...

WebThe Shannon-Nyquist sampling theorem states that a signal must be sampled at a rate which is at least twice that of its highest frequency component. If a signal contains power at frequencies higher than half the sampling rate, these high frequency components will appear in the sampled data at lower frequencies and will distort the recording.
