Alberto,

For many articles like this, I visit a local college engineering
library which has subscriptions to these periodicals, and make copies.
Maybe that is an option for you.

Hi Alberto,
  this is a great Newsgroup, isn't it?

These guys have helped me out so *many* times!

It beats paying a DSP consultant $100 per hour.

Rick,
   you can bet on it! Though I am mainly a lurker, this NG has helped
me many times, by just reading answers to questions posed by others.
And the S/N ratio is one of the greatest that you could ever hope for
an Internet newsgroup.

A Peaceful (we need it) New Year 2004 to everybody
