Two major impairments which affect the cable television picture quality are the thermal noise and the composite triple beats (CTB). We introduce a novel CTB reducing scheme which reduces the visual effect of CTB significantly. This in turn allows cable operators to boost up signal levels so as to reduce the thermal noise, thus improve the picture quality of their cable systems
