ABSTRACT:
A circuit for controlling the polarity of an asymmetrical waveform, such as a typical audio waveform, is described. The circuit provides smooth polarity switching with substantially no audible switching sound. The smooth switching results from switching each frequency of the audio signal at a different time. The circuit is particularly useful in a peak-limiting apparatus such as those often used in AM broadcasting.
