ABSTRACT:
A high speed arrangement for simultaneously demodulating the AM and FM information coming in on a tone frequency carrier. In the case of the incoming tone signal being only FM modulated, the FM demodulator extracts the data whereas the AM demodulator provides an output which can be used to squelch the FM demodulated data channel when noise or interference reaches a predetermined level.
