In a logic circuit, two inputs A and B are applied to an AND gate, and the output of the AND gate is connected to the input of a NOT gate. If the inputs A and B are both at logic 0, what will be the output of the entire circuit?

The question describes a circuit composed of an AND gate followed by a NOT gate. Let's analyze the logic:
- AND Gate: An AND gate outputs 1 (true) only if both inputs are 1 (true). Otherwise, it outputs 0 (false).
- NOT Gate (Inverter): A NOT gate inverts the input. If the input is 1, the output is 0; if the input is 0, the output is 1.
Given that inputs A and B are both 0, let's trace the signal through the circuit:
- AND Gate Input: A = 0, B = 0
- AND Gate Output: Since both inputs to the AND gate are 0, the output of the AND gate is 0.
- NOT Gate Input: The output of the AND gate (0) becomes the input to the NOT gate.
- NOT Gate Output: The NOT gate inverts the input 0, resulting in an output of 1.
Therefore, the final output of the entire circuit is 1.
