摘要
ＦＸＺ选频系统是采取先确定两通信点之间的最大可用频率ＭＵＦ值，然后在０．８５ＭＵＦ～１．０ＭＵＦ之间寻找最佳频率点。主要介绍选频系统中回波时延值的确定、ＭＵＦ值的确定、频率控制码的形成及其有关的接口电路。
FXZ frequency selecting system first confirms the highest frequency which can be used between two communication points,which names MUF value,then finds a best frequency point between 085 and 10MUF.This paper mostly introduces the confirmation of electric wave delay\,the confirmation of MUF values\,the form of frequency\|controlling code and the relative interface circuits in detecting system.
