想問一下binary要怎麼表示5,7的half

4.5
Design a combinational circuit with three inputs x, y, and z, and three outputs, A, B, and C.
When the binary input is 0, 1, 2, or 3, the binary output is twice the input. When the binary
input is 4, 5, 6, or 7, the binary output is half the input.

Binary is simply expressed as high and low signal.If there are 4 output pins,you can select one of them to represent the 0.5. When that pin fires,it presents as 0.5.So this problem is using the binary 4 pin as input to switch between twice and half mode.
