The output from a NAND gate is divided into two in parallel and fed to another NAND gate. The resulting gate is a

1. NOT gate
2. AND gate
3. NOR gate
4. OR gate

Correct answer: AND gate

Solution

When the output of a NAND gate is fed into both inputs of another NAND gate, the resulting operation is equivalent to an AND gate. This is because the double inversion cancels out, leaving the AND operation.
