Christian,<BR /><BR />The final value selection depends on how much damping you want to add to the signal you are windowing. More decay equates to a reduction in peak amplitudes and wider frequency peaks. A good explanation of the use of an exponential window can be found at the following link.<BR /><BR />http://thesagesite.com/papers/dave_qa/q&afeb9.pdf <BR />Wed, 02 Jan 2002 15:16:33 GMTLBoltzmann2002-01-02T15:16:33ZExponential window

Hi!<BR /><BR />I just read the Application Note 041 by National Instruments, but there<BR />are still some questions I have. Perhaps you can help me:<BR />- In Labview the Exponential window is defined as y=x*exp(ai),<BR />a=ln(f)/(n-1). f is the final value.... what's that? Normally 0, isn't<BR />it????<BR />- Each window like Hanning, Hamming etc. needs a scaling factor;<BR />probably the exponential window too.? And how can I calculate this<BR />factor?<BR /><BR />Thanks<BR />Christian <BR />Mon, 31 Dec 2001 13:06:11 GMThttps://forums.ni.com/t5/LabVIEW/Exponential-window/m-p/31473#M20772Christian Guenther2001-12-31T13:06:11ZRe: Exponential window
