I'm in the process of writing a report that includes rise time measurements, and I can't seem to find where the convention of rise time defined as 10-90% of bilevel comes from... It seems rather arbitrary to me. It seems like a poorly founded standard for over damped systems.
I see that the 2.2*tau for RC rise time is derived from the 10-90%, but where does the 10-90% itself derive from?
Any knowledge/thoughts would be appreciated!
