H03M3/482 - 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

Sub-classes:

H03M3/484 » {by adapting the gain of the feedback signal, e.g. by adapting the reference values of the digital/analogue converter in the feedback path} 31
