frequency response correction

[paganini]

I measure vibrations with an accelerometer.
The frequency response under 10 Hz is not linear according thae calibration sheet of the sensor.I want to correct it whith labview
Can you tell me a way to do that
thanks

The question is "How to linearise the sensor response" not "How to do this in LabVIEW".

You need to figure out how to perform the mathematics first, and then implement it in LabVIEW. Once you know the mathematics required, the rest is easy.

You need to place an equation between your acquired data and the values you require (linearised). The equation you have to find yourself, as it is a characteristic of your sensor.

Hope this helps

Hello Paganini,

As Shoneille says, you need first to found the mathematical algorithm that can correct your data and then search the corresponding VIs in LV.
You can also try to use some LabVIEW functions that process signal. You can found these functions in "Functions Palette>>Analyse>>Signal Processing" or "Functions Palette>>Analyse>>Mathematics"

Hope this help.
