## Rise Time given Damped Natural Frequency Formula

Rise Time = (pi-Phase Shift)/Damped natural frequency
tr = (pi-Φ)/ωd

## What is rise time?

Rise time is the time taken for a signal to cross a specified lower voltage threshold followed by a specified upper voltage threshold. This is an important parameter in both digital and analog systems. In digital systems it describes how long a signal spends in the intermediate state between two valid logic levels. In analog systems it specifies the time taken for the output to rise from one specified level to another when the input is driven by an ideal edge with zero rise time. This indicates how well the system preserves a fast transition in the input signal.
