Abstract: 948,462. Stereophonic systems. PHILCO CORPORATION. April 7,1960 [April 8, 1959], No. 12382/60. Heading H4L. In a receiver for single channel stereophonic signals comprising a common carrier wave and four sidebands, the beat of the reference signal of the receiver and the carrier frequency is eliminated without affecting the programme level by applying to synchronous detector 48 the stereophonic signal and a reference oscillation from the oscillator 50 to give a resultant signal (A+B) a Beat (if the carrier wave and reference frequencies differ) which is combined by adder 60 with an inverted signal -(A+B) from amplitude detector 34. The resultant Beat signal squelches synchronous detector 46 normally feeding - (A - B)+Beat to the output adders 26, 36 and its cut-out results in monaural (A+B) output at speakers 30, 40. The phase difference producing the beat reacts also on phase comparator circuit 66 (Fig. 5, not shown), its output being fed to reactance tube 70 which is coupled to and regulates the frequency of oscillator 50 (Fig. 6, not shown), removing the Beat and restoring the stereophonic output A and B. In a modification (Fig. 8, not shown), two synchronous detectors combine the stereophonic signal with the reference signal and appropriate phase shifts to give A+Beat and B+Beat signals which are combined and inverted to give -(A+B)+Beat and further combined with the output of the envelope detector to give a Beat signal utilized as before.
