Detailed explanation3: Sometimes you need to AND more than two inputs together. In fact, 3and 4input AND gates are just as common as the dualinput variety.
Detailed explanation4: 3 input NAND Gate The Boolean expression of the logic NAND gate is represented as the binary operation dot(.). Where A, B, and C are the inputs and Y is the output.
Detailed explanation5: Explanation: Realizing the expression requires 1 AND gate represented by ‘. ‘ and 1 OR gate represented by ‘+’.
