Hi,


I intend to re-sample an Analog Input signal sampled at 10000Hz to 6000Hz.


At the moment, the "Resampler type" option in the Export signals list is shown as "Disabled". See attached pic.


Please can you advice on how I can enable it?

Dear Dino, 

Thank you for contacting us. 


Re-sampling to a custom rate can only be carried out for a lower rate than the starting rate. 

It is available when you want to export file(s), you can do like this.


“Resempler type” is disable by default, you have to set “Export rate (Hz)” before, then you will see Auto which you can choose between three resampler types : Alias free, Linear or Hold.



The previously available resampler functionality can also be used when using the multi-file export.


For any additional information, please don’t hesitate to contact us.


Kind regards,

Damien.

Thanks for the info....I am trying to resample from 10000Hz to 6000Hz. The "Export rate (Hz)" cell doesn't accept a value of 6000. However, it accepts 5000 and other multiples of my sampling rate of 10000Hz. Does that mean your custom rate has to be a multiple of the sampling rate?

Dear Dino Morio,


Resampling here will remove points from the initial sample. So your first sample rate needs to be a multiple of the sampling rate you wish now. In your case, 5000 is the closest.


Kind regards,

Damien.
