H03M3/486 - 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 input gain
