Question

Implement a switching network that has two data inputs (A and B), two data outputs (C and D), and a control input (S). If S equals 1, the network is in pass-through mode, and C should equal A, and D should equal B. If S equals 0, the network is in crossing mode, and C should equal B, and D should equal A.

Short answer

Switching network:

Step-by-step solution

Determine the logical network and switching network

The switching network will have the selector that selects the inputs and the outputs as per the signal. The logical functions are the combinations of the inputs and outputs of the truth table. The inputs be operated through the logical operators and the outputs are processed. Each Boolean expression can be represented through gates and the combinational circuits. The logical functions or expressions can be written from the conditions of the input and the output provided.

Determine the switching network

Given that the two data inputs A and B , two data outputs C and D. The selector is the control input S.

If S equals 1, the network will be in pass through mode. C should equal A, D should equal B.

If S equals 0, the network is in crossing mode, and C must equals B, D must equals A.
