Re: Filter Bank

a filterbank consists of both analysis and synthesis part....

look for the type of filter bank needed

then u must have an downsampler in the analysis part and some filters as per ur needs

and an exactly opposite filter to that used in analysis part must be used in the synthesis part along with a upsampler

i dont remember the function name properly.
