butterworth filter

[Kktm3030!]

Hi guys, i need help to develop Butterworth filter.. I cant find the block diagram..(refer to my attachment with circle)...

According to your Attachment ... oops, I can't find the attachment.  What "edition" of LabVIEW have you installed?  I believe the Filters require at least the Full edition ...

If you can't find the block diagram, we have a problem. Have you tried "menu...windows...show block diagram". If it's not there, maybe you are using the control editor by accident.

Can you take a step back and explain what you are trying to do? What are you trying to filter and why?

While it can be done, of course, a Butterworth filter  is available (LabVIEW full and above), so there is no need to "develop" your own from scratch.

Hi Sir, thanks for your feedback.. i just to know the block diagram....i put in the word file with circle.. i cant found it...

I cannot clearly "see" the image of the missing Block Diagram function you show in your Word document.  However, I see you generating Butterworth Coefficients, but not using them with the IIC Cascade Filters (bottom row on the Advanced IIR Filtering VIs).  Might they be what you are missing?
