Detailed explanation-1: -NOT gates are to be added to the inputs of which gate to convert it to a NAND gate? The NOT gates are to be added to the inputs of OR gate, it will give the NAND gate output.
Detailed explanation-2: -The algebraic expression of the AND to NAND Gate conversion is Y=A’+B’. The algebraic expression of the NOR gate is Y=A’. B’. After complement, we get the expression of the And gate.
Detailed explanation-3: -The NAND gate operates as an AND gate followed by a NOT gate. It acts in the manner of the logical operation “and” followed by negation. The output is “false” if both inputs are “true.” Otherwise, the output is “true."
Detailed explanation-4: -NAND gate is actually a combination of two logic gates i.e. AND gate followed by NOT gate. So its output is complement of the output of an AND gate.This gate can have minimum two inputs. By using only NAND gates, we can realize all logic functions: AND, OR, NOT, Ex-OR, Ex-NOR, NOR.
Detailed explanation-5: -In digital electronics, a NAND gate (NOT-AND) is a logic gate which produces an output which is false only if all its inputs are true; thus its output is complement to that of an AND gate.
