NTE1801

NTE1801 Integrated Circuit TV dbx Noise Reduction System Description: The NTE1801 Multiplexed Sound dbx Noise Reduction Decoder is a single–chip linear IC in a 28–Lead DIP type package suitable for US NTSC System use. The device incorporates two RMS– 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.
