STEREO DEMODULATOR SYSTEM ABSTRACT OF THE DISCLOSURE A stereo demodulator system includes first and second differential amplifiers differentially responding to a first form of a stereo signal and at least a pair of differentially connected transistors serially connected to the output circuit of the first differential amplifier and responding to a second signal related to the first signal. A current mirror circuit is provided from the output circuit of the second differential amplifier to the pair of differentially connected transistors to produce a mixed output signal at the output terminal of the pair of transistors to separate the stereo signal into com- ponent signals. An offset current compensator is provided to avoid producing an offset current in the mixed output signal.
