Half Subtractor And Full Subtractor. Similarly the borrow output of first half subtractor is ored with the borrow output of second half subtractor to get the borrow output of full subtractor. The difference output of first half subtractor is ex or of a and b.

The difference output of full subtractor is ex or of b in and output of first half subtractor. And the borrow output just needs two additional inputs da and db. Full subtractor also belongs to the class of a combinational circuit and is used to perform subtraction of two binary bits.
The difference output of full subtractor is ex or of b in and output of first half subtractor.
The difference output of first half subtractor is ex or of a and b. Full subtractor also belongs to the class of a combinational circuit and is used to perform subtraction of two binary bits. Similarly the borrow output of first half subtractor is ored with the borrow output of second half subtractor to get the borrow output of full subtractor. The half subtractor can only be used for subtraction of lsb bits but if there occurs a case of borrow during subtraction of lsb bits then it can have affected over subtraction in higher columns.
