Filter signals below amplitude

[ThomB]

Hello again,

I have another probable rookie question. I am wanting to write a program that filters signals below a certain amplitude, but allows the rest to pass, I've tried doing the attached but its not working, or the chart isnt scaling to show it?

My ultimate intention is to analyse live wind speeds with a DAQ that is not yet installed. I'd like to test the program im going to use with historic data as a simulated signal, so I can swap it straight out when the time comes.

Anyone have any ideas where I'm going wrong? (I've saved the .lvm file as a text to allow upload, first colum time second results)

Many thanks

Thom

Is this the right approach? Or not appropriate for signal data?

I think you have the right idea in general

I am not sure what the comparison and selector functions actually do with the Dynamic Data.

If you convert the data to an array, it will do what you want.
