integration of imported signals

[Claire]

I want to import a test signal from an excel spreadsheet and integrate it. I can import the signal but I can't integrate it. I have tried to use the integral.vi but it keeps coming up as zero.

Did you remember to enter your dt value (inverse of sample rate) into the Integral.vi? The VI needs that information to integrate correctly.

The attached VI shows a simple example where dt is set to 10ms corresponding to a sample rate of 100 Hz.

Thank you very much. That was very helpful.
