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; Structural details of digital delta-sigma modulators characterised by the order of the loop filter, e.g. having a first order loop filter in the feedforward path the modulator being of the error feedback type, i.e. having loop filter stages in the feedback path only
