Abstract

In the adjustment, particularly the step-by-step adjustment of the volume of audio signals, audible and thus interfering clicking noises are produced due to the abrupt change in the signal variation when C-MOS switches are used. This interference is suppressed by the fact that, by the beginning of each step-by-step level change, a signal jump of the same magnitude is generated in the opposite direction which initially compensates for the signal jump. After a predeterminable time constant has elapsed, this compensation is cancelled again in a continuously decreasing manner until a new level jump arrives. Control of the volume of audio signals. <IMAGE>
