H03M7/3011 - CPC Classification

Classification description:

Conversion of a code where information is represented by a given sequence or number of digits to a code where the same, similar or subset of information is represented by a different sequence or number of digits; Compression ; Expansion; Suppression of unnecessary data, e.g. redundancy reduction; Conversion to or from differential modulation; Digital delta-sigma modulation; Compensating for, or preventing of, undesired influence of physical parameters of non-linear distortion, e.g. by temporarily adapting the operation upon detection of instability conditions
