- The full subtractor is a combinational circuit with three inputs A, B and Bin and two outputs D and Bo. A is the minuend, B is the subtrahend, Bin is the borrow produced by the previous state. D is the difference output and Bo is the Borrow output.

The truth table of full subtractor is as follows:

| Inputs | Outputs | |--------|---------|

A | B | Bin | A-B-Bin | Bo |
---|---|---|---|---|

0 | 0 | 0 | 0 | 0 |

0 | 0 | 1 | 1 | 1 |

0 | 1 | 0 | 1 | 1 |
