<p>14 A system for reducing audible noise in a stereo receiver includes a stereo demodulator having a monophonic signal output and a difference signal output. There is a left signal combiner and a right signal combiner. At least one filter having a controllable variable cutoff frequency intercouples at least one of the difference signal output and the monophonic signal output with the left and right combiners. A control signal generator has a control signal output coupled to the control signal input of the variable cutoff frequency filter.</p> |
