本文提出的设计方法是基于这样一个原则:即在要求的信噪比下,取得尽量高的接收机灵敏度,确定合理器件类型及其参数。作者应用此工程设计方法,设计了一部广播电视光接收机,设计参数与试制结果基本一致。
The design method proposed in this paper is based on the principle that as much as possible receiver sensitivity is obtained under the required signal-to-noise ratio to determine the type of device and its parameters. Using this engineering design method, the author designed a radio and television receiver, the design parameters and trial results are basically the same.
