Question
Design a 1-bit adder/subtractor with an "Op" control input.
When Op = 1 => it should work like half-adder, (x+y)
When Op 0 => it should work like a half-subtractor, (x-y)
You need to add/subtract two bits, x and y, according to input value of "Op". Derive the truth table
performing ,kmap,functions and logic diagram.
x+y when input value of Op is 1 and
x-y when input value of Op is 0
