本文讨论采用4端口定阻网络理论设计单管同轴电缆载波系统基本增音机方向滤波器的DeSoer综合方法,采用这种方法直接综合的4端口方向滤波器、与我国目前所采用分析法设计的同样的网络比较,具有质量好、元件省,体积小、和可靠性高等十分显著的优点。文中并给出设计实例,和实际达到的各项质量指标。
This dissertation discusses the DeSoer synthesis method of designing the basic directional filter of single-tube coaxial cable carrier system based on the theory of 4-port fixed impedance network. Using this method, a direct synthesis of 4-port directional filter is compared with the current analytical method used in China The same network comparison, with good quality, component province, small size, and high reliability of the very significant advantages. The article gives the design examples, and the actual quality indicators.
