Question

With the help of symbol diagram of AND gate, prepare its truth table.

Hint:

Remember: AND means multiplication in Boolean algebra.

Answer 1

Step 1: Symbol of AND Gate

The AND gate has two or more inputs and one output. Its symbol is represented as:

\[ \text{(Insert AND gate diagram: two inputs A, B and one output Y)} \]

Step 2: Logical Expression

The logical expression for the AND gate is:

\[ Y = A \cdot B \]

Step 3: Construct Truth Table

The truth table for the AND gate is given below:

Input A	Input B	Output (Y = A ⋅ B)
0	0	0
0	1	0
1	0	0
1	1	1

Step 4: Conclusion

The AND gate output is HIGH (1) only when both inputs are HIGH. If either or both inputs are LOW (0), the output remains LOW (0).
