The foremost disadvantage of the half subtractor is, we cannot make a Borrow bit in this subtractor. The full subtractor block diagram is shown below. The designing of this can be done by two half subtractors, which involves three inputs such as minuend, subtrahend, and borrow, borrow bit among the inputs is obtained from the subtraction of two binary digits and is subtracted from the next higher-order pair of bits, outputs as difference and borrow. In this article, we are going to discuss its construction using half subtractor and also the terms like truth table. Many combinational circuits are available in integrated circuit technology namely adders, encoders, decoders, and multiplexers. It is a combinational logic circuit used in digital electronics. It is an electronic device or logic circuit which performs subtraction of two binary digits. Here we are discussing the full subtractor. Subtractors are classified into two types like half subtractor and full subtractor.
