H03M1/0665 - 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 time domain, e.g. using intended jitter as a dither signal by continuously permuting the elements used, i.e. dynamic element matching using data dependent selection of the elements, e.g. data weighted averaging
