MyDaQ Highpass lowpass response

[AymanB95]

Hello there,

im really new to Labview and im trying my best.i have a NI myDAQ and i have a Filter bank connected to it (Filter bank contains Highpassfilter + lowpassfilter in DIO ports). my goal is to generate a signal and to plot the highpass and lowpass response to it. I am not allowed to use the Elvismx functions (Function generator+ oscilloscope). 

i know that its not complicated, but im really new to this and i have no clue 😞

i thought maybe to do somthing like the screenshots, does it look like a good start?

could someone help me? i would really be thankful for any help!!!

thanks in advance!

In those screenshots (showing only smaller parts of your whole code) you just read from AI channels.

How does that relate to your goal of "generating a signal"? How does it relate to "filter bank in DIO ports"???

Why do you use the "hardware timed single point" acquisition mode?

Why do you need to read 2 samples in the upper image, just to compare to two different limt values? (Why do you need a sequence frame here?)

Why do you need two IndexArray nodes in the lower image? Why not just resize IndexArray to read both samples/channels?

Hi GerdW,

i used these screenshots as an example, i didnt write the code but i thought that it could work on my problem. The problem is, i never worked with myDaQ and i didnt found good examples for my problem. when i search about my problem: all people use the Elvismx modules (the function generator vi and oscilloscope vi).

i would really be thankful for any suggestions !!

Best regards,

Ayman
