RESULTS: here (after final test attempt 1).

Final test attempt 2 (and LAST!): Thu, 31.01.2001, 12:15, room 120.
Yes, you may come if you simply want to earn a better score. But beware -
there will be some PENALTY if your score is lower than at 1st attempt. (Don't come unprepared!)

The free book in pdf   is  there: http://www.dspguide.com/pdfbook.htm

The book, as far as I've "investigated" superficially, can be valuable --
at least as a quick reference.

Please remember:
1) there are notation differences between lecture and dspguide
2) The official book is Oppenheim & Schafer (though notation is
sometimes different too)
3) no book is obligatory in these circumstances

Probably the best choice is to buy O&S, 1999 edition, which was
lately seen in KMPiK bookstore (,,Sciana Wschodnia''), for about 100 PLN.
It'll serve you for years, if you are interested in DSP. And it contains a lot of PROBLEMS to solve and learn!

Or you may prefer to buy/borrow a laboratory scriptbook, which is in
polish language (Cyfrowe Przetwarzanie Sygnałów, red. A Wojtkiewicz, wydawnictwa PW)
