If you want a good introduction to numerical techniques that does not overwhelm you with theory, try the Numerical Recipes series. I still have a copy of Numerical Recipes in C I bought in grad school many years ago. Older versions (newer than the one I have ) are available online here. The older, obsolete versions are fully available to anyone. The nice thing is that virtually all the algorithms have been implemented natively in LabVIEW, so you don't have to write them yourself, just use them. Have fun!

Norbert,
Thank you so much! It helps a lot.

Thank you.
I tried to isolate the signal using a "low-level" way.
Here is the route :raw data(time domain)——FFT——data(frequency domain)——isolate the signal(set the intensity of the frequencies that i am not interestedin to zero)——inverse FFT ——to get filtered data(in time domain).
I think my spectrum is better now.
Thanks again!

It's a great news since I will have many homeassignments on labview later this semester.
Thanks a lot.

Is this related to your other misplaced posts?

Here's the last version of the VI that the OP posted saved as 2011 VI. Please note that the OP last wrote on this thread in September and it is unlikely that he is still monitoring it. Please create a new thread with questions relating to your issue.

sorry dude.
I have to find fft for the time domain of frequency 50 hz,
I don't know that part. Pls help me friends..... My program may be absolutely wrong. But pls help me out.
My datas are here... Pls note this and get me fft for the time domain
