| Abstract: | There is cross and mutual modulation interference in circulating CATV. According to the transmission features of wave and the non--linear distortion of amplifier, this paper approaches the physical principle of the formation of the interference. Based on the praetical expriences,some counter measures are proposed to improve the interferenceand the image quality in circulating CATV. |
