I've tried to debug my filterbank in two ways,but i could'nt understand what went wrong. (i)I put a sinusoid tone of frequency 3000 into my filterbank algorithm and expected to see the energy in the 2 or 3 band but strangely I see energy in all the bands. - I don't have any clue, sorry. (ii) I took 32 input samples ,did the analysis filtering ,then i had 32 samples each sample corresponding to a subband,and I passed it directly through the synthesis part,but I could'nt get back the original. - Good experiment. Filter bank is process is lossy, we can't regenerate the signal back from filter outputs. In literature the error is specified as 0.07dB, if my memory is correct. Can anybody tell me what is happening. Thanks in advance. -Hima. ===== Himachandra Chebrolu University Of Kentucky Lexington,KY-40506 -------------------------------------- "Don't go through life but grow through life..." --------------------------------------- __________________________________________________ Yahoo!
