filter complex number

[valentina.alina]

Hello,

Is there a way to (bandpass) filter complex signals in Labview? I googled it but i do not seem to find a way to filter complex signals (a+i*b).

Edit: The normal bandpass filter block won't work because it does not accept complex input

Split it into re/im, filter individually, recombine.

I'm sorry if this is a dumb question but is it correct (mathematically) to do so?
