<br>Hi,<br><br>I would like to compute the inverse FFT of the MDF coefficients. I have noticed that some coefficients are obviously missing since I do not see the mirror effect, neither find the purely real frequency 0 coefficent that have to be found for a "real" signal.<br>I guess the frequency 0 coefficient is 0 (average energy 0), but how should I do the mirroring and how many coefficients should I expect ?<br><br>Thanks,<br><br>David<br><br><br /><hr />Avec Windows Live Messenger restez en contact avec tous vos amis ! <a href='http://www.windowslive.fr/messenger/' target='_new'>Téléchargez Messenger, c'est gratuit !</a></body>
