Circuit Description
The component contains two separate FM sound IF sections for television stereo applications
or for multistandard receivers. Each FM section consists of an eight-stage symmetrical limiter
amplifier followed by a coincidence demodulator and an AF pre-amplifier with a low-ohmic
output. The component features considerably improved AM suppression characteristics with
small input signals, as well as a very low frequency deviation between THD min and AM min.
