Binary Subtractor used for Binary Subtraction from www.electronics-tutorials.ws

The half subtractor is a combinational circuit that is used to subtracts two bits. Since the difference output of a subtractor is given by ab'. The block diagram of a half subtractor is shown below in fig.1.

Half subtractor is a combination circuit with two inputs and two outputs (difference and borrow).

The logic table for a full adder is slightly more complicated than the tables we have used before, because now we have 3 input bits. The logic symbol of half subtractor is represented in the diagram below. Half subtractor is a combination circuit with two inputs and two outputs (difference and borrow). A and b, which subtract two input binary digits and generate two binary outputs i.e.
