control amplitude of vibration

[gyver.ning@gmail.com]

Hello, friends.

I am searching a vi, that can return a average value of amplitude (or peak to peak value ) of vibration signal (a sinusoidal signal) in a certain period of time, for example ,1S, 0.5S. I have used the '' Amplitude and Level Measurement.vi'', but it only return the difference between maximum positiv value and minimum peak value. it is, however, not a average value. can you give me some advise?

thank you  very much.

Hey Gyver, 

I would use the Waveform Peak Detection VI in the Waveform Monitoring VIs Pallette. It finds the locations and amplitudes of peaks and valleys in Signal In and outputs an array of all the amplitudes of each peak. You can then average that array using the mean VI. Let me know if this helps!
