Figure 1 shows the block diagram for the NTE789. The input signal form the detector is amplified by a lowdistortion
preamplifier and simultaneously applied to both signal, generated by a local voltagecontrolled oscillator
(VCO), is counted down by two frequency dividers to a 38kHz signal and to two 19kHz pilottone supplied
by the FM detector is compared to the locally generated 19kHz signal in a synchronous detector...
