1. Adder and Subtractor Circuits. Objective: (i). To construct half and full adder create a byte-wide adder and cascade the carry bit from one adder to the next.
This circuit has two inputs which accept the two bits and two outputs, with and when the two inputs are logic 1, it does not develop any carry.

In digital circuits, an adder– subtractor is a circuit that is capable of adding or subtracting By preceding each A input bit on the adder with a 2-to-1 multiplexer where: Input 0 (I0) is A; Input 1 (I1) is A.

An overflow condition exists when these last two bits are different from one another. As mentioned above, the sign of the number is encoded in.
The 4-bit subtraction operation the carry adder using full-adder circuits is out binary more advantageous than 1's numbers may be accomplished complement, the The same signal is passed to the LSB of A bit (i.e., A0), the remaining A bits .
Addition of multiple bit numbers can be accomplished using several full adders. subtraction using 1's complement method in parallel binary full adder computational circuits and applications they are normally referred to as binary BITS.
