can you tell more about calculating the derivate and checking for large derivate sample values

Did you learn some basic math at school?

Derivative is defined as dx/dt, so you calculate the difference between one sample and the next, then multiply by your sample rate (which is the same as 1/dt)…

You really ask "how to check for large values"? Ever looked at the comparison functions palette?

Calculus is not basic math (but derivatives are basic calculus).  You could be a bit gentler with your instruction, maybe?

Hi Bill,

I learned basic calculus (derivatives and integrals) in school…
