摘要
利用传输线理论对射频传输线的传输特性进行分析 ,指出阻抗匹配对射频信号能量传输的影响 ,并就闭路电视系统中使用的典型电缆为例从不同方面分析其衰减的情况 。
The great influence of impedance match on the transmission of the RF signal energy is pointed out after analyzing the transmitting characteristics of the transmission lines in terms of the transmission line theory.The paper focuses on the factors that affect the attenuation of the typical cable used in closed circuit television system and provide the reference data to select proper cable.
