## Rise Time Formula

The following formula is used to calculate the rise time of a second order system.

t = 2.09439 / w_{d}

- Where t is the rise time
- w
_{d}is the damped frequency (rad/s)

## Rise Time Definition

A rise time is defined as the time it takes for a damped signal to change from a low to high value.

## Rise Time Example

How to calculate rise time?

**First, determine the damped frequency.**Calculate the damped frequency.

**Finally, calculate the rise time.**Calculate the rise time using the formula above.

## FAQ

**What is a rise time?**

The rise time is considered the total amount of time it takes for a signal to change from a low value to a high value. These are most often involved in electronics when describing voltage or current step functions.

**What is a damped frequency?**

A damped frequency is the frequency of an underdamped harmonic oscillator.
