H03M3/36 - 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

Sub-classes:

H03M3/362 » {in feedback mode, e.g. by reducing the order of the modulator} 12
H03M3/366 » {in feed-forward mode, e.g. using look-ahead circuits} 13
