UWB五阶高斯脉冲信号发生源代码，用于生成UWB信号(UWB Gausinn 5th Derivetive)

设计一个一位二进制数大小比较器。比较两个一位二进制数A和B的大小，电路有三个输出端Y1，Y2和Y3，分别对应A大于B，A等于B，A小于B。当条件满足时，相应输出端为1，否则为0。（A，B用两个脉冲源代替），建立仿真模型并保存。(Design a one binary magnitude comparator. A size comparison of two binary numbers A and B, the circuit has three outputs Y1, Y2 and Y3, respectively, corresponding to the A greater than B, A is equal to B, A less than B. When the conditions are met, the corresponding output is 1, and 0 otherwise. (A, B instead of the source with two pulses), and save the simulation model.)
