可以实现一下四项指标的程序1．设计8路脉冲信号发生器，其脉宽和频率均可调。

2．其中6路信号的频率同步可调，频率范围在0.1HZ-1MHZ，步进值自行设置。

3．其中2路信号的频率相同，但有相位差，2路信号的相位差用按键可调，步进值自行设置。

4． LED显示器上自动显示信号的频率值。-Can achieve the four indicators of the program. Design 8-channel pulse signal generator, the pulse width and frequency can be adjusted. Two. 6 signal frequency synchronization adjustable frequency range in 0.1HZ-1MHZ, the step value to set. 3. 2-way signal frequency is the same, but the phase difference, the phase difference of the 2-way adjustable with buttons, to set the step value. 4. The LED display automatically displays the value of the frequency of the signal.
