闭路传输 meaning in English

close circuited transmission

In the design and application of electronic engineering , both in open circuit and in closed circuit , signal is certainly affected by environment , the status of the transport network and the change of the parameters of the components applied . then the characters of useful information will be changed more or less and the change is generally called as distortion , namely so - called signal distortion
<中文摘要> =在电子工程的设计和应用中，信号无论在开路传输或闭路传输中都受到环境、传输网络的工作状态和应用的元器件参数变化的影响，从而会或多或少地改变有用信息的性质，这种变化就是所谓的信号畸变现象，通常称作失真。
