H03M3/362 - CPC Classification

Classification description:

Conversion of analogue values to or from differential modulation; Delta-sigma modulation; Continuously compensating for, or preventing, undesired influence of physical parameters of non-linear distortion, e.g. instability by temporarily adapting the operation upon detection of instability conditions in feedback mode, e.g. by reducing the order of the modulator
