Implement the circuit of Problem 4.13 using appropriate multiplexers.
In your design in Problem 4.12, what happens if both the control signals are at 0 and a clock pulse comes along? Redesign the circuit (if necessary) to prevent the clearing of register C under the above conditions. Feed the output of C to its input). What type of flip-flop should C be made of?
There are three 2-bit registers A, B, and C. Design the logic to perform:
XOR and NAND are control signals. Each bit in the register is a D flip-flop.
