Advanced Medium Voltage
AM Stereo Decoder
applications. The circuits and functions included in the design allow
implementation of a full–featured C–QUAM AM stereo radio with relatively
few, inexpensive external parts. It is available in either 28–lead DIP or EIAJ
compatible wide–bodied 28–lead SOIC. Functionally, the MC13022A and
MC13022 are very similar. The MC13022A has 10 dB more audio output and
a CMOS compatible logic level output (Pin 15) for stop sense. The stop
sense/AGC function has been internally connected to the output notch filter
control.

... L–R component that makes them more annoying than would ordinarily be expected for the measured level. The MC13022A measures the interference level and reduces L–R as interference increases, blending smoothly to monaural. The pilot indicator remains on as long as a pilot signal is detected, even when interference is severe, to minimize annoying pilot light flickering ...
