Pdm to analog converter

SpletA PDM bitstream is encodedfrom an analog signal through the process of delta-sigma modulation. This process uses a one-bit quantizerthat produces either a 1 or 0 depending on the amplitude of the analog signal. A 1 or 0 corresponds to a signal that is all the way up or all the way down, respectively. SpletHigh-performance audio analog-to-digital converters (ADCs) with best-in-class sound quality ...
