How to implement the expression of discrete transfer function on the LabVIEW FPGA side?

[王佳]

I have only found this node, named Nifpga Discrete Transfer Function Direct.vi, but after inputting the transfer function coefficients, its output doesn't work correctly. I tried the same discrete transfer function on the non-FPGA side, and it worked fine. I am not sure what the issue is. Are there other methods to implement a discrete transfer function?
