Thank you for the explanation @Akansh.

I agree with you @Akansh.

The rise time of a certain pulse is 5 microseconds if the amplitude of the pulse is 5v and its baseline 0v determine the actual change in voltage during the rise time.

(0 to 10) % of time is delay time because input pulse changed after some time output is changed so i.e. is delay time and 10%to 90%of time is rise time.

Thanks akansh.

In electronics, when describing a voltage or current step function, rise time refers to the time required for a signal to change from a specified low value to a specified high value. Typically, in analog electronics, these values are 10% and 90% of the step height: in control theory applications, according to Levine (1996, p. 158) , rise time is defined as "the time required for the response to rise from x% to y% of its final value", with 0%-100% rise time common for under damped second order systems, 5%-95% for critically damped and 10%-90% for over damped. [1] The output signal of a system is characterized also by fall time: both parameters depend on rise and fall times of input signal and on the characteristics of the system.

In control theory, for overdamped systems, rise time is commonly defined as the time for a waveform to go from 10% to 90% of its final value.

Why not from the base line to 90%?

Why rise point is from 10%?

Why its not from 0-90 or 0-100% ?
