How to Create Adder, LPF and HPF, Amplifier Circuits in FPGA LabVIEW

umair1998 over 1 year ago

Hello, I have NI cRIO 9024 with NI 9215 and NI 9263.

I want to design a digital signal processing circuit with the following sequence

From Sensor 04 Voltages will be Received at AI0-3 Module > I want to Add These 04 Signals > Amplified Them > Pass Them Through Low Pass Filter >> Normalize My Final Output

Currently, all the above operations are being performed by Analog Circuit which contains opamps, resistors, and capacitors. How can I replace all these using LabVIEW?

I don't know if my Question is posted on the right platform or not but I am not sure how to ask for help. Please someone should suggest me how to start with my task.

Thank you all

Best Regards

Umair

Hi,

This is the FPGA group, and it's not relevant to your question. I might be wrong, but LabVIEW should have graphical elements that can sum and filter. You create a flow using those graphical elements.

There's lots of lessons here: /products/devtools/ni-labview/rt/roadtests/642/a_beginner_-_course_in_labview_and_test_automation?ICID=HP-labviewDCH-rotationbanner#pifragment-7188=4&pifragment-7189=7

You'll definitely want to check out the dataflow lesson there (it's a video). But, if you're asking this question, then you should go through all the lessons there.

I have experience with LabVIEW but I want to use FPGA for digital signal processing

I don't think that the NI modules you mention as being available to you include an FPGA.

I don't use NI parts so I may have misread their documents but I suggest that you check that you can access an FPGA before committing to that path. The NI FPGA hardware is not cheap and that might be a barrier to you if you need new parts.

michaelkellett I have all the NI Modules which I mentioned above.

Apparently, the FPGA is in the chassis that the modules plug into.

I couldn't find any data on that model which explicitly stated that. Most of the current models (the 9024 is not available any more) do include an FPGA and make quite sure that you know about it.

The reference is in this document:

It looks like it was sold as a bundle. If Umair didn't source the modules like that, then it might be wise to check that the chassis has that functionality.
