dear members, Can anybody of you please clarify the meaning of "time- resolution" and "frequency-resolution" in the context of time- frequency analysis of signal? WHAT DO THEY ACTUALLY MEAN? And how one is traded off against the other? I know that "Heisenberg's uncertainty principle" is there... but, I am unable to visualize it. Earnestly, looking forward to your reply, Thanking you, Sincerely yours, Kausik |

I think as an introduction, it is best to read: http://engineering.rowan.edu/~polikar/WAVELETS/WTtutorial.html and http://cas.ensmp.fr/~chaplais/Wavetour_presentation/Wavetour_presentation_US.htm\ l Kind regards, Filip Rooms Ghent University Department for Telecommunication and Information Processing (TELIN) Sint-Pietersnieuwstraat 41, B-9000, Gent, Belgium Tel: +32 (0)9/264 34 15 Fax: +32 (0)9/264 42 95 http://telin.rug.ac.be/~frooms/ "Absolutely nothing should be concluded from these figures except that no conclusion can be drawn from them."
