Hi,
I have three analog outputs from an accelerometer, (x, y, z axis)
What I would like to get is the amplitude of the resultant vector. (direction not necessesary)
Would like to keep everything analog.
We are measuring the impact of an offshore race boat on the water after a jump, so there is no need to be extremely accurate.
Signals are 1.65 V at rest, varying up and down in motion.
I would like to work with instrumentation opamps, since I know those best. (well, only thing I reasonably know....)
All help, links etc welcome.
Regards, Geert-Jan
