Half Subtractors
Similar to the adder, we can also design subtractors and we also have half and full subtractors. Half subtractor (HS): This circuit subtracts two bits and gives Borrow and Difference as 2 outputs. The following table shows the result for different combinations of inputs: a b B(borrow) D(difference)= D = a – b 0 0 0 […]
