Energy loss of spectra associated with Window Functions

  1. Dec 3, 2007 #1
    I'm doing research on window functions (such as: rectangular, Hanning, Blackman, etc), but am having trouble with respect to the energy loss associated with each. I know that applying the window causes energy loss in the spectra of interest, and for the Hanning Window and Hamming window, multiplying the FFT by 1.633 and 1.586 respectively offsets this a bit.

    How were these two correction factors calculated, and what are the correction factors for other window types?

    Please note: I posted this in the EE forum but it probably belongs here.
