There is so much. But if I had to limit myself to just one thing above all else it would be to look at the signal. Does it look like you expect it? Is it clipped? Did we actually measure anything? of many automatic systems "assume" the signal is good. Generally the most used signal processing is frequency analysis - see for example http://blog.prosig.com/2003/07/29/notes-on-fourier-analysis/ what this class of analysis does is to express the information in term of frequencies as this is often easier to appreciate and to determine the origin. Here you have to distinguish between random data, transient data and periodic data. Each has a different progeny method; they all use Fourier analysis of course but in different ways. Also no basic discerning signal processing is complete without considering aliasing. Colin Wow - what a question to ask a signal processor! There is so much.

You say this is in conjunction with vibration balancing. Actually we have <a href="http://www.prosig.com/dats/optbalance.html" rel="nofollow">extensive multiplane balancing software</a> that is available with DATS. If you could explain your application a little more I may be able to help. Colin qundeel
