Half Subtractor Pin Diagram. The diff and borrow are two output states of the half subtractor. This circuit is used to subtract two single bit binary numbers a and b.
The block diagram of the half subtractor is shown above. The diff and borrow are two output states of the half subtractor. A and b which subtract two input binary digits and generate two binary outputs i e.
Block diagram truth table.
The half subtractor hs circuit has two inputs. From the above difference and barrow equations we can design the half subtractor circuit diagram using the k map. The block diagram of the half subtractor is shown above. A and b which subtract two input binary digits and generate two binary outputs i e.
