I know that an RC low pass filter has a rise-time computed as (ln(0.9)-ln(0.1))RC, or approximately 2.2RC.
When adding additional orders to the filter -- or changing the response (i.e Bessel, Chebyshev, etc.) -- what is the effect on the rise-time computation?
Sorry, I'm too tired to do the math today.
