H03M3/484 - CPC Classification

Classification description:

Conversion of analogue values to or from differential modulation; Delta-sigma modulation; Analogue/digital converters using delta-sigma modulation as an intermediate step; Means for controlling the correspondence between the range of the input signal and the range of signals the converter can handle; Means for out-of-range indication characterised by the type of range control, e.g. limiting by adapting the quantisation step size by adapting the gain of the feedback signal, e.g. by adapting the reference values of the digital/analogue converter in the feedback path
