Abstract:
A method of calculating spectrum estimates comprising:collecting timestamped data over a computer network, and calculating spectrum estimates using a Continuous Fourier Transform where the spectrum estimates F(&ohgr;) of data samples having values xi timestamped at time ti are calculated as F&it;â€ƒ&it;(Ï‰)=1(2&it;â€ƒ&it;Ï€)3/2&it;â€ƒ&it;Ï‰&it;â€ƒ&it;j&it;â€ƒ&it;&Sum;i=0N-1&it;â€ƒ&it;(&ee;2&it;â€ƒ&it;Ï€&it;â€ƒ&it;j&it;â€ƒ&it;Ï‰i+1-&ee;2&it;â€ƒ&it;Ï€&it;â€ƒ&it;j&it;â€ƒ&it;Ï‰i)&it;â€ƒ&it;xi.
