说明: 在本系统中,信息序列在先经过FSK调制,经过截止频率为25kHz的低通滤波器后(把信号频率限制在25kHz),再进入混频器搬移到更高的频率发送出去,在接收端,用与发送端同步的跳频信号对其进行变频(跳频的解跳处理在此进行),取下边频,然后进行FSK的解调(In this system, the message sequence prior through FSK modulation, through the cut-off frequency of 25kHz after low-pass filter (to limit the frequency 25kHz), and then move into the mixer to a higher frequency to send out, at the receiving end used with frequency hopping synchronization signal transmitter carried on their conversion (FH' s solution to deal with this for jumping), take down side frequencies, then the demodulation of FSK)
