  1. Name: Help! Discovered a big bug of labview's ChirpZ Transform function(Not Sure) Submitter: bodopoq Submitted: 04 Dec 2014 Category: *Uncertified* LabVIEW Version: 2012 License Type: BSD (Most common) When using ChirpZ transform of LabVIEW(The example itself provides),I found a strange thing.When the frequency is very big and the range is small together with a not small number of ChirpZ transform,Error happened(very bad spectrum and wrong frequency ChirpZ's result is)! Nothing is wrong with the examples(I've scripted other VIs to verify this),and this error didn't happend using MATLAB. So I believe that is a bug of LabVIEW!!!(Not Sure yet of course). I Need Help!

  2. Met this problem for a long time, and wait for the NI Technical supporter's final feedback for a long time. Need an immediately solution. Maybe anyone who knows a better way to refine spectrum, may you gave me a help

Is there any error? Or is there a bug of LabVIEW's ChirpZ tansform? I've already uploaded the codes and screenshot.May you have a look.
