Design a 4-bit adder-subtractor circuit using the 4-bit binary Full adders (74LS83) and any necessary additional logic gates. The circuit has a mode input bit, M, that controls its operation. Specifically, when M=0, the circuit becomes a 4-bit adder, and when M=1, the circuit becomes a 4-bit subtractor that performs the operation A plus the 2’s complement of B.Where A and B are two 4-bits binary numbers. That is, * When M=0, we perform A+B, and we assume that both...

Adder Start out by picking 2 positive six bit binary numbers that are less than 3210, written in 2's complement notation. The eventual goal is to add these two numbers. 1) Look at the LSB bit of the numbers, and using logic gates (NANDs, NORs, etc.) design a circuit that correctly gives the right output for any possible combination of bits in the LSB place. 2) Now look at the next column to the left (next to LSB). In this...
