Half Subtractor. A half subtractor is known as a combinational circuit that produces a difference of two 1 bit binary numbers. Half subtractor is a combinational logic circuit used for the purpose of subtracting two single bit numbers.
The half subtractor is designed with the help of the following logic gates. More specifically we can say that it subtracts the two binary values at its input in order to generate a difference of the two values at its output using a borrow bit if required. Circuit of half subtractor truth table of half subtractor.
Quite similar to the half adder a half subtractor subtracts two 1 bit binary numbers to give two outputs difference and borrow.
We use half subtractor to subtract the lsb of the subtrahend to the lsb of the minuend when one binary number is subtracted from another. Circuit of half subtractor truth table of half subtractor. It has two inputs minuend and subtrahend and two outputs difference d and borrows bout. Parallel adder and parallel subtractor.
