Question

The time required for a gate or inverter to change its state is called __________

(a) Rise time

(b) Decay time

(c) Propagation time

(d) Charging time

This question was posed to me in a job interview.

My doubt is from Quine McCluskey or Tabular Method of Minimization of Logic Functions in section Boolean Algebra and Minimization Techniques and Logic Gates of Digital Circuits

Answer 1

Correct choice is (c) Propagation time

To elaborate: The time required for a gate or inverter to change its state is called propagation time.
