Hi,

I have some instantaneous raw data sampled every 1.25ms, which consists of harmonics.

Is there a way to programmatically get another array of same size (1740x1), with only the fundamental (50Hz) component values?

Also, I do not have the signal processing toolbox. Is there a way without making use of it?

Any help will be much appreciated.

Regards,

Varun

Hi,

I have found a solution, which is more of a fix...

Passing the array to the "From Workspace" block in a model file and further passing that data into the Fourier Block (powerlib_meascontrol/Measurements/Fourier) where we can enter the fundamental frequency and order, and finally again getting the data in the workspace through "To Workspace", which gives the data processed by the Fourier Block.

Cumbersome, but does the trick...

I'm open for a better approach...
