downsampling vi

[BSharmi]

Hi,

I want to reduce the downsampling rate of a signal from 100k (I/Q acuisition rate is 100k) to around 40-50 Hz.I used the downsampling vi and added a decimation factor of about 2000. How do I reconstruct the downsampled signal? I have the decimateda array and the value of 'dt' of the original but what will be the value of 'dt' for the new decimated signal?  is it 0.02?

can anyone please help?

Thanks

Please post your VI along with some typical data saved as default.  It is difficult to diagnose the problem from a brief verbal description.  Also tell us what the downsampled signal should look like, so that we do not need to guess.  If there are errors in what you have done, it is possible that reconstruction cannot be performed.
