Full Subtractor Diagram. In the case of a half subtractor a input is complemented similar things are carried out in full subtractor. Full subtractor circuit diagram with logic gates the circuit diagram of the full subtractor using basic gate s is shown in the following block diagram.
The outputs of the full subtractor are d and bo. As we know that the half subtractor produces two outputs i e diff and borrow. In the case of a half subtractor a input is complemented similar things are carried out in full subtractor.
Full subtractor overcomes the limitation of half subtractor.
The above block diagram describes the construction of the full subtractor circuit. The above block diagram describes the construction of the full subtractor circuit. In the case of a half subtractor a input is complemented similar things are carried out in full subtractor. A full subtractor fs is a combinational circuit that performs a subtraction between two bits taking into account borrow of the lower significant stage.
