Poisson summation and Parsevals identity

  1. Sep 28, 2004 #1
    I've heard something about Poisson summation in relation to Fourier analysis, but I can't seem to find any good info on the subject... Can anyone explain what "Poisson summation" is?

    Furthermore, I would like to know exactly what "Parsevals identity" states and how it is applied.

    Thanks.

    These kinds of indentities relate the coefficients of the series to the function, usually in terms of integrals.

    I can't recall the exact wording of hte relevant theorems, but if you go to

    www.dpmms.cam.ac.uk

    go to people, find tom koerner's link and onhis personal web page shld be some very good notes on fourier analysis
