I hope all is well. If I understand correctly, you are trying to simultaneously filter two different arrays of data, which means that the same filter parameters (low pass/high pass, cutoff frequency) will be applied to both arrays of data. One of the ways to achieve this would be to use a "Merge Signals" to merge both the current and voltage data and pass the resulting signal into the Filter Express VI. When I tried this, I was able to view both filtered data at the same time. Please feel to try this and let me know if it answers your question.

Rudi: It sounds like you have the idea of what I am trying to do. My problem has been the "init/cont" mode setting for the filter since I have several arrays. I can filter this way:
Voltage (init) -> voltage (cont) -> voltage (cont) -> votlage (cont) ...
and then
Current (init) -> current (cont) -> current (cont) -> current (cont) ...
But what I want to do is:
Voltage (init filter 1) -> Current (init filter 2) -> Voltage (cont filter 1) -> Current (cont filter 2) -> ... and so on
I will try the merging, it would be something like:
Voltage & Current (init) -> Voltage & Current (cont) -> ... that will be easy enough if it works!
Thanks,
