Questions & Answers

Q: What is the logical symbol for the AND gate?

The logical symbol for the AND gate is represented by a symbol with two inputs and one output, resembling a multiplication sign.

Q: How many possible input combinations are there for an AND gate with two inputs?

There are four possible input combinations for an AND gate with two inputs, which are 00, 01, 10, and 11 in binary terms.

Q: What is the output of an AND gate when one of the inputs is 0?

When one of the inputs to an AND gate is 0, the output will always be 0, as the logical multiplication requires all inputs to be high (1) to produce a high output.

Q: Can you explain the truth table for an AND gate with detailed examples?

In the truth table for an AND gate, output (Y) is 0 when either or both inputs are 0, and the output is 1 only when both inputs are high (1).
