NTE1056 Integrated Circuit FM Stereo Multiplex Demodulator Description: The NTE1056 is a monolithic integrated circuit FM multiplex stereo demodulator designed for use in FM stereos, phonographs and radio receivers.
A multiplex stereo demodulator circuit generally concom sists of four main circuits, a composite signal amplifier, 19KHz pilot signal filter, 38KHz subcarrier generator and either a matrix or a switching circuit which seperates the composite signal into the right and left audio channels.
In addition to these circuits, an automatic stereo−monaural switching circuit, stereo signal indicator circuit, muting circuit, separation control circuit and SCA circuit are also...
