SYV型同轴电缆的多路电视传输 MULTIPLE TRANSMISSION OF TV SIGNALS BY A SYV-TYPE COAXIAL CABLE 保宗悌 Bao Zongdi Wang Tingzhu first-author 王挺柱 本文首先对SYV—78—5—1型同轴电缆的特性,在理论上进行分析,着重研究它的振幅和相位的频率响应,并用实验加以验证。同时研究它对不同频率的屏蔽特性。其次,对已试验成功的两路电视传输系统的电路设计作了扼要的阐述。 The characteristics of a SYV—75—5—1 type coaxial cable are described, The amplitude and phase responses of this cable are given through theoretical analysis and refilled by experimental measurement, Its screening effect for various frequencies is investigated. In addition, the design of a two-way TV Signal transmission system, which has proved to be useful in practice, is briefly described. 1980-03-01 2021-04-01 3
