The NTE1801 Multiplexed Sound dbx Noise Reduction Decoder is a single鈥揷hip linear IC in a
28鈥揕ead DIP type package suitable for US NTSC System use. The device incorporates two RMS鈥?/div>
level sensors and VCA circuits, as well as five operational amplifiers and two buffer circuits.
A complete multiplexed sound system for US NTSC System television sets can be built by interfacing
the NTE1801 with the NTE1800 Multiplexed Sound Decoder.
