H03M1/0641 - CPC Classification

Classification description:

Analogue/digital conversion; Digital/analogue conversion; Continuously compensating for, or preventing, undesired influence of physical parameters characterised by the use of methods or means not specific to a particular type of detrimental influence by averaging out the errors, e.g. using sliding scale in the amplitude domain using dither, e.g. using triangular or sawtooth waveforms the dither being a random signal
