摘要
根据跳时PPM信号的特点,提出了产生跳时PPM信号的系统设计方案,对系统的各部分组成进行了详细的分析。给出了PPM产生器的顶层电路图并对时序进行了仿真,给出了时序的仿真波形。最后对电路进行了调试,调试结果显示:由示波器能够看到输出256 kHz的时钟信号、伪码、信码和PPM信号。
According to the characteristic of time hopping PPM signal,it proposes integral system designing project about produced time hopping PPM signal,the structure division of system is introduced in detail. PPM generating routine top circuit diagram is given and timing sequence is simulated. Finally,it debugs the circuit,debugging result ,shows output 256 kHz clock signal,pseudo code,code and PPM signal through oscillograph.
