Question

Propagation delay of a 3-input AND gate refers to:

a) The time taken for the output to change after a change in inputs.
b) The delay in the gate's power-up sequence.
c) The time it takes for the gate to reset.
d) The time required to initialize the gate.

Answer 1

The propagation delay of a 3-input AND gate is the time taken for the output to change following a change in the inputs, a key specification for digital circuit design.

Step-by-step explanation:

The propagation delay of a 3-input AND gate refers to a) The time taken for the output to change after a change in inputs. When there is a change at the input of a logic gate, there is a finite period of time before the output reflects this change. This delay is due to the physical and electrical properties of the components within the gate. Propagation delay is an essential specification for understanding the timing and performance characteristics of digital circuits, especially when building complex systems where signals need to be precisely synchronized.
