C-Quam AM Stereo Decoder MC13028

Labels: >> >> >> >>
This electronic circuit is AM stereo decoder that accepts the signal from the IF of a receiver (450 or 455 KHz) and decodes stereo medium wave broadcasts. It operates at 8-15VDC and provides standard level left and right audio output for direct connection to the audio amplifier.

It may be used to support 30Hz-15KHz audio but it depends on the bandwidth of the receiver's IF.
