Question
The logic functionality realized by the circuit shown below is ____________
The correct answer is
AND
The circuit shown in the image represents an AND gate. Let’s analyze the circuit to understand why the output is AND:
- In a digital circuit, an AND gate gives a high output (1) only when all its inputs are high (1). For two inputs, A and B, the output Y will be 1 if and only if both A = 1 and B = 1.
- From the given circuit, notice the arrangement of the switches. For the circuit to complete and the output Y to be high, the following conditions must be met:
- Both switches corresponding to inputs A and B must be closed (i.e., logically 1).
- If either input A or B is 0, the path will not be completed, making the output Y 0. Therefore, this setup forms an AND logic condition.
Thus, the functionality realized by the circuit is an AND gate.
