Abstract

A description is given of the design of a bipolar analog integrated circuit (IC) which contains the most important filters and all the stages for decoding the multichannel TV sound baseband signals according to the Broadcasting Television System Committee (BTSC) system specification. The IC decodes the composite baseband signal derived from a broadband 4.5 MHz FM demodulator. The baseband signal enters on the composite input, is level-adjusted and applied simultaneously to second audio program (SAP) and MPX decoders. In accordance with the listener´s choice, either the demodulated dbx-encoded left-right (L-R) signal or the SAP signal can be switched to the internal dbx decoder.
