Hi all,
I am running the Simulate->Analysis->Fourier Analysis of multisim
But it always shows "wavelength longer than time span" after a few minutes of simulation, what does it mean ? Thanks.
P.S. My circuit has two signal source(100Hz and 1000Hz) and I want to see the frequency response of the whole system.
My setting in Fourier analysis :

Hi Nate,
Could you post up your schematics so that we can do further analysis?

Hi Derek,
As attahced, look forward to you help !!!

Hi Nate,
Maybe you can try the following settings:
Frequency resolution: 60K
# of harmonics: 5
End time: 0.0001
You should be able to get something reasonbale then. Hope that helps.

Hi Derek,
I still get the same error message with your setting. And I would like to observe the frequency response with finer frequency resolution, that is why I set the frequency resolution as low as 10Hz. The frequency response that I interested is like this :
Do you have any suggestion on this ?
Thanks anyway.
