| Abstract: | High quality stereo and dual sound for a TV receiver require improvements in the dynamienoise performance and the intercarrier buzz. This paper analyses the intercarrier buzz phenomenon in TVreceiver and describes a Quasi-Split SIF system and the design of TV receiver for BTSC multichannel soundwith single-chip Zenith-dbx decoder. |
