Rate of change calculation
« on: February 14, 2013, 11:43:34 PM »
I'm trying to figure out how to calculate the rate of change of an S16 signal.  Any suggestions?  Thanks.

Here is a quick version of how I did this a few times, you can play with the sample time and period to see the change at different intervals.

Hi,

maybe another way?
Time is variable by the temp rise.
