Once solution could be to audit a course at your local university, even though it's probably going to be focused on the academic side I believe that a strong understanding of the underlying principles always helps.

I think that MIT has some opencourseware stuff about it as well http://ocw.mit.edu/courses/electrical-engineering-and-comput...

again that's probably mostly the theory behind the implementations and not how to use them.
