Description: In this video, the Half Subtractor and Full Subtractor are explained in detail. By watching this video, you will learn what is half and full subtractors and how to implement a full subtractor using half subtractors. Timestamps: 0:00 Half Subtractor 3:34 Full Subtractor 11:11 Full Subtractor using Half Subtractors What is Half Subtractor? It is the combinational circuit that performs the subtraction of two input bits and generates the difference and borrow bits as an output. The logic circuit of the Half subtractor consists of one two-input XOR gate (Difference output) and, one AND gate and NOT gate (Borrow Output). The Boolean expression of Difference and Borrow output of Half Subtractor: D = A (XOR) B (The difference output) B = A'B. (The borrow output) The half-subtractor circuit can perform the subtraction of two one-bit numbers without any borrow input. It is suitable for the subtraction of the two one-bit numbers at the LSB positions. Full Subtractor: The Full-subtractor is the combinational circuit that performs the subtraction of two input bits and the incoming borrow bit and generates the difference and the borrow bits as an output. The Boolean expression of Difference and Borrow output of Full Subtractor: D = A (XOR) B (XOR) Bin Bout = A'B + Bin [ A (XOR) B ] ' The Full Subtractor circuit can be implemented using the two Half Subtractors and one OR gate. In this video, the design of Full Subtractors using Half Subtractors is also explained.
