Draw a circuit to implement a switching network with two data inputs (A and B), two data outputs (C and D), and a control input (S). If S=1, the network is in pass-through mode: C=A and D=B. If S=0, the network is in crossing mode: C=B, and D=A. Use the most reasonable combinational building blocks or gates. Label the inputs and outputs.

Question

Draw a circuit to implement a switching network with two data inputs (A and B), two data outputs (C and D), and a control input (S). If S=1, the network is in pass-through mode: C=A and D=B. If S=0, the network is in crossing mode: C=B, and D=A. Use the most reasonable combinational building blocks or gates. Label the inputs and outputs.

Expert Solution
Step 1: Introduction

Combinational circuit is a type of circuit which consists of input variables and output variables. These circuits does not depends on the previous inputs to generate output like sequential circuits. It can have any number of inputs and any number of outputs.
