Analog filter? Once the data is in labView, it's all digital, I'm not sure what you mean by "Analog" in this case. To me, an analog filter is made of things like real-life resistors, capacitors, inductors, amplifiers, etc.

If you just want to filter out some noise out of your signal in labView, you'd be using a digital filter. LabView has some pretty advanced filter tools but I think there is a "PID Control Input Filter" in the PID Palette that's pretty handy and easy to use: hook up your noisy signal to the input, and you should get an output signal with less noise.

You can use the PID Control Input Filter even if you are not using any other PID features.

good luck!
