自己写的pwm占空比采集与输出 但是没有计算占空比，如果又需要可以自己修改计算并显示占空比，该程序已经测试过了，可以使用，拿出来供大家分享，新手写的如有不足请大牛带飞。

代码实现了一个根升余弦成型滤波器，2PAM信号通过此成型滤波器，并且匹配接收，画出了发送和接收波形，验证了代码的正确性。(The code designs a root raised cosine filter,2PAM signal transmitted through the filter and matched using the same filter, I plot the transmitted signal and received signal to verify the correctness of the code.)

实现了四bit计数器的功能，使用的是VHDL语言描述(Four-bit counter, using the VHDL language description)
