hi

I am a first year research student, i am studying multirate systems, and filter banks.
can anyone give me infotmation on practical use of multirate systems in the industry ,
and if anyone who used such systems.

email:adnani@uk.ac.strathclyde.eee.spd 

thanks.

Multirate filterbanks are used in high quality digitial audio coding,
as for example ASPEC, DOLBY AC-2 and ISO/MPEG-AUDIO.
Very common is the modified discrete cosine transform (MDCT, also
called LOT - lapped orthogonal transform).               

An overview is given in:
Th.Sporer, Kh.Brandenburg,B.Edler: The use of multirate filter banks for 
coding of high quality digital audio. In: Signal Processing VI-Theories
and Applications, Proceedings of EUSIPCO-92, Bruessel 1992.

In addition to my previous posting i want to emphasize:
coding of high quality digital audio is only one application,
there are more important applications (as f.i. picture coding).
Sorry if my posting before caused an wrong impression about possible
applications of multirate filter banks.
