Analog Read Signal

[tpcurran]

Hi

I am reading in a signal (voltage) from serial port from a vibration sensor (MEMS) into Labview, my signal is very "noisy" in the waveform chart, is there any way of smoothing it out to read approx zero when there is no vibration?

The signal from the sensor is voltage dc and to convert to g its: output reading minus zero output (3.84) divided by sensitivity (40mV/g)

See attached files..

Also how would go about creating graph in the frequency domain?

thanks

In the palettes you might have Signal Processing >> filters which should give you a good way to smooth your signal out. I'm not sure if this is included in all versions of LV.
You can also find Signal Processing >> transforms for the FFT into frequency domain.
