.Come up with a full sub-tractor truth table with Input numbers B being subtracted from A, taking care of any Bin, giving the difference D and Borrow out Bout [9 MARKS] .From the truth table draw the combination circuit for the difference D and Borrow out Bout [4 MARKS] . For the circuit in figure 3, 3.3.1. 3.3.2. find the expression for X [3 MARKS] What should be the values of A, B and C be for X=1?
