Subject[Cs-dev] mac and maca
Hi,
I spotted something that looked wrong in mac and maca. Checking the
sources, I think it should be like this:
Syntax
ares mac asig1, ksig1 [, asig2] [, ksig2] [, asig3] [, ksig3] [...]
 
Performance
ksig1, etc. -- k-rate input signals 
asig1, etc. -- a-rate input signals 
mac multiplies and accumulates a- and k-rate signals. It is equivalent
to: 

         ares = asig1*ksig1 + asig2*ksig2 + asig3*ksig3 + ...


Can someone confirm?

Thanks,
Andrés

Yes; that is the correct version.  Certainly what the code does.
