NTE789 Integrated Circuit Stereo Multiplex Decoder Description: The NTE789, a monolithic silicon integrated circuit, is a stereo multiplex decoder intended for FM multiplex systems. This stereo multiplex decoder requires only one low- inductance tuning coil (requires only one adjustment for plete alignment), provides automatic stereo switching, energizes a stereo indicator lamp, and operates from a wide range of voltage supplies. Figure 1 shows the block diagram for the NTE789. The input signal form the detector is amplified by a low- distortion preamplifier and simultaneously applied to both signal, generated by a local voltage- controlled oscillator (VCO), is counted down by two...
