problem in filter

[detech]

I try to test filter.vi. I generate a noise signal and feed into filter. It always show freqency problem. I understand there is a restriction with sampling rate and sampling number. But I could not figure it out. Please take a look at my vi.

Thanks a Lot

You've made a couple of fundamental mistakes. First, you have pass parameters to the noise function that does not generate an error. The -1 for a mean created an error and there was no output. Second, you need to create a waveform data type before you wire the noise output to the filter. Make the mods as shown below and see if you get what you expect.
