Delay time is the time required by a system to reach a quarter of its steady state value.

A. True

B. False

This question was addressed to me in exam.

This intriguing question comes from Time Response of Control Systems in division Control System Applications of MATLAB

The correct answer is B. False

The explanation: The delay time is defined as the time required by the system to reach half of its steady state value. Hence, the above statement is false.
