ABSTRACT OF THE DISCLOSURE A dividing circuit for dividing a received AM stereo signal, which has been multiplied by a distortion correcting signal cos .PHI., by the distortion correcting signal, including a first differential amplifier comprised of first and second transitors, the bases of the transistors being supplied with the received AM stereo signal, at least one transistor for supplying the distortion correcting signal to either the emitters or collectors of the first and second transistors, at least one diode connected between the collector of the first transistor and a reference voltage source and between the collector of the second transistor and the reference voltage source, a current source connected in parallel with each at least one diode for maintaining the emitter resistances of the transistors at a small constant value, and a second differential amplifier connected in cascade with the first differential amplifier for producing the divided output signal of the dividing circuit.
