MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -A full adder circuit is central to most digital circuits that perform addition or subtraction. It is so called because it adds together two binary digits, plus a carry-in digit to produce a sum and carry-out digit. It therefore has three inputs and two outputs.

Detailed explanation-2: -Design a circuit that will function as a two bit adder. It will have four inputs and three outputs.

Detailed explanation-3: -"Two Bit Full Adders are the Logical Circuits that have two inputs for the input bits and one for the carry and as a result, Sum of the bits along with the carry are obtained at sum and carry Terminals respectively.

Detailed explanation-4: -The full adder is a three-input and two output combinational circuit.

Detailed explanation-5: -C-in is a carry from a less significant digit and c-out is a carry from the most significant bit. If we want to add two n-bit binary adders then it requires 1 half adder and n-1 full adder to complete the circuit.
