Need help designing a FIR Filter

[BobAlfredSmith]

Hello. I need to use a FIR filter to showcase it filtering a simulated signal. I am not sure how I can improve it, I am trying to use the resources given by my University, but they use a symbol that I cannot find in LabView. 

Could you help me figuring out what symbol it is? And if possible, some advice that would help me make a better looking FIR VI. Thank you.

That is, I think, a poor picture of a Bundle function (used to construct a LabVIEW Cluster, in this case one having an Integer (I32), Double (Dbl), and an Array of Dbl ([], with the orange color designating "Float", highly likely to be a Dbl).

I think you need to learn LabVIEW.  There are tutorials listed on the first page of the Forums that would have made the Symbol "obvious".  My advice on making a better FIR VI is to Learn LabVIEW, and to Avoid Express VIs, and especially avoid Dynamic Data Wires (which you probably haven't heard about, and may not recognize in your code ...).
