sigma-delta converter

[‚sig·mə ‚del·tə kən′vərd·ər] (electronics) A class of electronic systems containing both analog and digital subsystems whose most common application is the conversion of analog signals to digital form, and vice versa, using pulse density modulation to create a high-rate stream of single-amplitude pulses in either case. Also known as delta-sigma converter.

sigma-delta converter

A circuit that generates a 1-bit pulse density modulated (PDM) signal from analog input. It creates fixed-width pulses in relation to the amplitude of the analog waveform. As the wave amplitude rises, 1's are produced. As it falls, 0's result. If it remains neutral, alternating 01's are created. See PDM and SACD.
