sirzrx Posted December 21, 2004 Report Share Posted December 21, 2004 im simulating a signal 440v (sine) and i wanna calculate the 3rd,5th & 7thHarmonic... if any easy way to calculate them? and add some noise? Quote Link to comment
todd Posted December 21, 2004 Report Share Posted December 21, 2004 How about this. From left to right: "Gaussian White Noise.vi", "Auto Power Spectrum.vi" and "Harmonic Analyzer.vi" Quote Link to comment

todd Posted December 23, 2004 Report Share Posted December 23, 2004 I found them by searching the Functions palette for "gaussian", "auto power" and "harmonic". I am using the PDS, however (e.g. add-on toolsets), and it seems like the toolset used to be listed in the search results. Is there a simple way to tell which vi's are part of a toolset? Perhaps just knowing which top-level function palette is enough. Quote Link to comment

todd Posted January 11, 2005 Report Share Posted January 11, 2005 Why not calculate all harmonics then index the arrays of amplitudes and frequencies? Quote Link to comment
i2dx Posted January 11, 2005 Report Share Posted January 11, 2005 Try Help-->Find Examples-->NI Example Finder-->Analyzing and Processing Signals-->Tone Measurements maxbe some of the examples there may answer your question ... Quote Link to comment
