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,

设计一个两位二进制数大小比较器。要求当二进制数A=A1A0大于二进制数B=B1B0时，电路输出为1，否则为0（A1，A0，B1，B0用四个脉冲源代替），建立仿真模型并保存。-Design a two binary magnitude comparator. Required when the binary number is greater than the binary number A = A1A0 B = B1B0, the circuit output is 1, otherwise 0
