CBSE Class 12 · 2000 · SemiconductorsVery Short Answer

Name the logic gate shown in the figure and write its truth table.

Answer: It is an AND gate: $00 \to 0, 10 \to 0, 01 \to 0, 11 \to 1$ .

Solution

The symbol shown is that of a two-input AND gate, whose output is

Y = A \cdot B

.
The output is

1

only when both inputs are

1

:

00 \to 0, 10 \to 0, 01 \to 0, 11 \to 1

.

Y = A \cdot B (AND gate)
