HALF SUBTRACTER - The circuit, which performs the subtraction of two binary numbers is known as Binary subtractor. Half subtractor is the most essential combinational logic circuit which is used in digital electronics. Basically, this is an electronic device or in other terms, we can say it as a logic circuit. Half subtractor is used to perform two binary digits subtraction.
In half subtraction, the process of subtraction is similar to arithmetic subtraction. In arithmetic subtraction the base 2 number system is used whereas in binary subtraction, binary numbers are used for subtraction. The resultant terms can be denoted with the difference and borrow.
As in binary subtraction, the major digit is 1, we can generate borrow while the subtrahend 1 is superior to minuend 0 and due to this, borrow will need.
FULL BINARY SUBTRACTOR - The main difference between the Full Subtractor and the previous Half Subtractor circuit is that a full subtractor has three inputs. The two single-bit data inputs X (minuend) and Y (subtrahend) the same as before plus an additional Borrow-in (B-in) input to receive the borrow generated
As the full subtractor circuit above represents two half subtractors cascaded together, the truth table for the full subtractor will have eight different input combinations as there are three input variables, the data bits, and the Borrow-in, BIN input. Also includes the difference output, D and the Borrow-out, BOUT bit
