Ebook: Schaum's Outline of Signals and Systems

I purchased this outline as a supplement for a class text Signals and Systems, by Alan Oppenheim. The information is a significant help and the instructor actually recommended this outline as she gives us some additional problems to try on our own that is similar to what we are doing in class. This is a great study aid. I am happy with the purchase, it's always great to see several different examples worked out so you can recognize what's going on.
