Logic Circuit Diagram Of Half Subtractor. Not or inverter gate. Where a and b are called minuend and subtrahend bits.
Here inputs are represented with a b and outputs are difference and borrow. And b in borrow in and b out borrow out. Half subtractor and full subtractor.
The truth table is divided into two parts.
The above circuit can be designed with ex or nand gates. A and b which subtract two input binary digits and generate two binary outputs i e. The word half before the subtractor signifies that it deals with only two 1 bit numbers it has nothing to do with the borrow from the previous stage the logic symbol of half subtractor is represented in the diagram below. Half subtractor definition block diagram truth table circuit diagram logic diagram boolean expression and equation are discussed.
