WebNyquist Theorem: The Nyquist Theorem, also known as the sampling theorem, is a principle that engineers follow in the digitization of analog signal s. For analog-to-digital conversion ( ADC ) to result in a faithful reproduction of the signal, slices, called samples , of the analog waveform must be taken frequently. The number of samples per ... Web20 sep. 2015 · Digital means that you quantize the information (measure a voltage level, assign logical values etc.) and transmit the numerical value instead of the actual analog value. This is most apparent in audio applications.
