Tie unused input high through pullup resistor.
To make a full subtractor, you need an XOR and a NAND gate.
xor and xnor gates are derived from not gate
yes... xor is derived gate from primary gates
To construct a 3-input XOR gate using 2-input XOR gates, you can connect the inputs in the following way: First, take two of the three inputs (let's call them A and B) and connect them to a 2-input XOR gate, producing an output (let's call it X). Then, connect the output X and the third input (C) to another 2-input XOR gate. The output of this second XOR gate will be the result of the 3-input XOR operation, effectively computing ( A \oplus B \oplus C ).
No, XOR gate is a not a universal gate. There are basically two universal gates NAND and NOR.
A full adder can be constructed using basic logic gates: XOR, AND, and OR gates. Specifically, two XOR gates are used to calculate the sum, while two AND gates and one OR gate are employed to determine the carry-out. The first XOR gate takes the two input bits, and the second XOR gate incorporates the carry-in. The AND gates handle the carry generation, with the OR gate combining the outputs to produce the final carry-out.
its not
a XOR bis equivalent to: (a AND NOT b) OR (b AND NOT a)
XOR (Exclusive OR) gate is exclusively for either. OR allows 10, 01, 11. XOR allows 10 or 01, but not 11.

the easiest way to make an xnor gate is with a 7486 (or equivalent) integrated circuit, a quad xor gate. connect the output of one gate to one in put of another gate. connect the other input of the second gate to Vcc. the second xor gate will then act as an inverter.
1 gate.
