- 2. Logic Gate A logic gate is an elementary building block of a digital circuit. Most logic gates have two inputs and one output.
- 3. What is Universal Logic Gates? A universal logic gate is a logic gate that can be used to construct all other logic gates. 1. NAND Gate 2. NOR Gate
- 4. NAND Gate NAND gate (negative-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 the AND gate.
- 5. NAND Gate Boolean Expression Truth Table
- 6. NAND Gate As Universal Gate NAND gate as NOT gate
- 7. NAND Gate As Universal Gate NAND gate as NOT gate
- 8. NAND Gate As Universal Gate NAND gate as AND gate
- 9. NAND Gate As Universal Gate NAND gate as OR gate
- 10. NAND Gate As Universal Gate NAND gate as AND gate
- 11. NAND Gate As Universal Gate So we can see that all the three basic gates can be made by only using NAND gates, that’s why this gate is called Universal Gate
- 12. Any Question??
