ABSTRACT:
A converter is coupled between the antenna and the RF stage of an FM stereophonic receiver to convert received AM stereo signals into FM stereo signals. A received AM stereo signal is translated to an IF signal, and decoded into two stereo signals. These signals are then encoded into a broadcast-type FM stereophonic signal which is coupled into the front end of an FM stereo receiver.
