Hi,

   This is not specifically about LAU stuff, at the first level

anyway, but it could be one of these days maybe.


   Mostly for fun and to keep my old brain exercised I'm playing with

coding a DSP multiband equalizer. The thing basically works, actually

works pretty well with more or less steady state data, but it doesn't

look at all good with big transients mostly due to ringing in my lower

range band pass filters.


   Does anyone know of any reasonably simple papers talking about

sorting out this sort of design problem?


   I suspect someone like Steve Harris has forgotten more than I'll

ever know about subject like this but I'm not sure he's here anymore.

Maybe there's someone else who's available to talk to me off list?


Thanks,

Mark
