H03M3/326 - CPC Classification

Classification description:

Conversion of analogue values to or from differential modulation; Delta-sigma modulation; Continuously compensating for, or preventing, undesired influence of physical parameters characterised by means or methods for compensating or preventing more than one type of error at a time, e.g. by synchronisation or using a ratiometric arrangement by averaging out the errors
