U4454B - Quasi-Split-Sound Processing and AM-Demodulator

Description

The U4454B quasi-split-sound processor is a bipolar integrated circuit for all FM-TV standards and NICAM sound systems.

For FM/NICAM the IC operates as QSS-mixer.

In case of AM sound the circuit can be used as AM demodulator.

Features
