ＣＡＴＶ系统中的频率均衡张慧斐文ＣＡＴＶ系统中使用的同轴电视电缆，在工作频率增高时对信号的衰减将明显增大，造成Ｕ频段比Ｖ频段信号衰减大，在同一频段中高段信号衰减比低段大。按照国标ＧＢ６５１０—８６《３０ＭＨＺ—１ＧＨＺ声音和电视信号的电视分配系统》的...
Frequency Equalization in CATV System ZHANG Hui-Fei The coaxial cable used in CATV system attenuates the signal significantly when the operating frequency is increased, resulting in a large attenuation of signal in the U-band compared to the V-band. In the same band, the high-band signal attenuation ratio Low section big. In accordance with the national standard GB6510-86 “30MHZ-1GHZ sound and television signal television distribution system” ...
