Please help resolve this math probelm in labview?

Question

I try to use fft and ifft to make a filter, to remove some frequencies and then convert to time domain. I have problems to do it. To make it simple I attach a lv 2009 example, which has two component 10 hz and 15 hz input.
Can you help me in removing 15 hz after FFT and then convert with IFFT. Just to check if only 10 hZ signal left after IFFT.
If you can give me an example like this, my problem will be solved.
Thanks
Liming

Did my question answered so far?
The software boards are NI product users helping other users. NI employees do monitor and often answer your questions, but there is no guarantee of service when using the discussion forums.
If you have a specific question that requires a timely response, you can formally enter a help request where an NI engineer will respond and take responsibility for answering your question(s).
NI employees can be identified on the discussion boards by the blue color of the bars below the user name. You and I (users) are in gold. You will see various shades of blue and gold that indicate the number and quality of the answers provided by that user.
To ask an NI for support, see this web page:

Since strong@ni is an NI employee and has attempted to answer your question, I would suggest that you continue working on your problem here in this thread.
