IPC: H04H40/36
Filed: 1982-04-06
Granted: 1988-04-06
Abstract: A radio receiver with AM stereo signal demodulator uses left and right channel sum and difference signals.  The design minimises noise burst interference and separation effects between left and right channels.  A tuner produces an intermediate frequency and a subsequent detector separates the summed left and right signal plus signal level information. The 'IF' is also fed to circuits which process the left and right difference signals.  The signal level information from the sum signal detectors is fed via a control circuit into the difference channel for phase modulation and comparison with the non-modulated signal and multiplication with it.
