H03M1/183 - CPC Classification

Classification description:

Analogue/digital conversion; Digital/analogue conversion; Analogue/digital converters; Automatic control for modifying the range of signals the converter can handle, e.g. gain ranging in feedback mode, i.e. by determining the range to be selected from one or more previous digital output values the feedback signal controlling the gain of an amplifier or attenuator preceding the analogue/digital converter
