This circuit is a complete one-chip full-feature AM stereo decoding and pilot detection system. It employs full-wave envelope signal detection at all times for the L + R signal, and decodes L– R signals only in the presence of valid stereo transmission. . q q q ~ No Adjustments, No Coils Few Peripheral Components True Full-Wave Envelope Detection for L+ R PLL Detection For L–R . 25 Hz Pilot Presence Required To Receive L– R q Pilot Acquisition Time 300 ms For Strong Signels, Time EMended For Noise Conditions To Prevent “Falsing” I .
