Reduktion von hörbarem Rauschen

摘要

A system for reducing audible noise in a stereo receiver includes a stereo demodulator (11) having a monophonic signal output and a difference signal output. A left signal combiner (12) and a right signal combiner (14) are provided. At least one filter (21), having a controllable variable cutoff frequency, intercouples at least one of the difference signal output and the monophonic signal output with the left (12) and right (14) combiners. A control signal generator (22) has a control signal output (26) coupled to the control signal input of the variable cutoff frequency filter.
