Which logic gate is equivalent to an AND gate followed by a NOT gate?
Correct Answer: NAND gate
- Step 1: Understand what an AND gate does. It takes two inputs and gives an output of 1 (true) only if both inputs are 1 (true).
- Step 2: Understand what a NOT gate does. It takes one input and inverts it, meaning if the input is 1 (true), the output is 0 (false), and vice versa.
- Step 3: Combine the AND gate and NOT gate. First, use the AND gate to get an output based on the two inputs.
- Step 4: Take the output from the AND gate and feed it into the NOT gate. This will invert the output of the AND gate.
- Step 5: The final output is what we call a NAND gate, which stands for 'NOT AND'. It gives an output of 0 (false) only if both inputs are 1 (true).
