Implement a circuit 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 shouldequal A. Draw the circuits using the standard logic gates (NAND, NOR, NOT, etc) as needed. Explain the working of the circuit.
We wish to design a digital system with two flip-flops, say B and C, and one 4-bit binarycounter A, in which the individual flip-flops are denoted by A4, A3, A2, A1. A start signal Sinitiates the system operation by clearing the counter A and flip-flop C, and settling flip-flop B toone. The counter is then incremented by one starting from the next clock pulse and continues toincrement until the operations stop. Counter bits A3 and A4 determine the sequence ofoperations:If A3 = 0, B is cleared to 0 and the count continues.If A3 = 1, B is set to 1; then if A4 = 0, the count continues, but if A4= 1, C is set to 1 on the nextclock pulse and the system stops counting.Then if S = 0, the system remains in the initial state, but if S = 1, the operation cycle repeats.(a) Draw the ASM Chart(b) Draw the equivalent one flip-flop per state
