need to decimate data to 600 Hz sampling rate

[Yves]

Hi

I'm a little bit stuck and confused about a problem.

I have acquired data with a sampling rate of 5kHz. Now I need to reduce them down to 600Hz.

(I have saved the data in a tdms file.)

Is there an easy way to do it? I tried the express vi "sample compression" but you can't set 8 1/3 as a reduction factor.

Of course another easy way would have been to acquire the data with a reduced sampling rate but unfortunately the NI 9237 module needs a minimum sampling rate of 15xx Hz.

Thanks for any help

You can try to use Resample Waveforms vi (with a factor of 3) and then use the sample compression with a reduction factor of 25.

Hi,

I think "resample waveform" is the way to go - but I think you shouldn't need anything else.

Just wire 1/600 to your dt input. This will reduce your output sampling rate to 600 Hz.

I'm really curious why you need to reduce the sampling rate. Care to share?
