H03M3/416 - 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 number of quantisers and their type and resolution having multiple quantisers arranged in cascaded loops, each of the second and further loops processing the quantisation error of the loop preceding it, i.e. multiple stage noise shaping [MASH] type all these quantisers being multiple bit quantisers
