This circuit may be used to eliminate possible distortion introduced into the AM stereo signals by changes in the DC level of one or both of the envelope signal and the in-phase signal. Since these two signals are com- pared to produce the cosine correction signal, any change in the relative DC levels will introduce distortion since it will be interpreted by the correction circuit as an error requiring correction.
