sub-band synthesis filter

Started by Sunil Shukla June 30, 2004
Hi,

Can anyone point out about sub-band synthesis filter used in DAB systems ?
I have the algorithm for sub-band analysis filter that is used in MPEG layer
II encoder.
But i am unable to understand how the reverse process is acheived with the
same parameters as that in encoder.

Thanks,
Sunil

I'm not sure about DAB or MPEG, but Crochiere & Rabiner's Multirate book has a good section on analysis/synthesis filters and polyphase implementation thereof. -- Mark
