H03M3/45 - CPC Classification

Classification description:

Conversion of analogue values to or from differential modulation; Delta-sigma modulation; Structural details of delta-sigma modulators, e.g. incremental delta-sigma modulators characterised by the order of the loop filter, e.g. error feedback type the modulator having a higher order loop filter in the feedforward path with distributed feedforward inputs, i.e. with forward paths from the modulator input to more than one filter stage
