Hi PF Designers,(adsbygoogle = window.adsbygoogle || []).push({});

Wasn't too sure if this would belong in the Electrical engineering forum but here goes.

I'm designing a prototype for my thesis that will read in sensory data wirelessly to a matlab script. This sensory data is riddled with noise, however important data is contained in the High frequency components of the signal as well.

Hence I was naturally going to use aSavitzky-Golay FIR filterin matlab. However I was wondering if I could perform further noise reduction techniques on top of this and still preserve the high frequency component that I saved.

Thoughts, dilemmas, discussion, tid bits of help?
