A digital audio signal is obtained by the suitable sampling and quantization of the electrical output of the microphone. Although any sampling frequency above 40 kHz would be adequate to capture the full range of audible frequen-cies, a widely used sampling rate is 44,100 Hz, which arose from the historical ...

sample rate of audio CDs by a large factor, and reduced the wordlength from 16 bits to 1 in a reasonable way, that would serve as the basis of a PDM system. Most current digital audio systems use multi-bit PCM (pulse code modulation) to represent the signal. PCM has the advantage of being easy to manipulate.
