To drivers convenience, the DCS technology of mobile radio transceivers is introdued with PC, channel parameter programming and signaling code programming, it is simple and straight-forward and is of low production costs.
为了司机操作方便,在车用通信机中引入数码静噪系统;用IBMPC对通信机信道参数及信令码进行编程,操作方法简单明了,且大幅度降低生产成本;用锁相环压控振荡器输出电压Uc对本振频率带宽跟踪补偿,可使带宽增加0。
