Full Adder using Half Adder A Full Adder can also be implemented using two half adders and one OR gate. The circuit diagram for this can be drawn as, And, it could be represented in block diagram as, The Boolean expression for Sum and Carry is as, ...
this subtractor circuit is very helpful to cascade single bit numbers and also subtracts more than two binary numbers. In such cases, a full adder cascaded circuit is used with the help of NOT logic gate. The conversion
