Current infos

The Exam2 is necessary, so we'll meet on Monday, 09 Feb 2004 in front of the room 447 and we will find a nice place to write the exam.

If you need some consultation (or just want to see your exam :-( ), I'll be available on Fri, 30 Jan, about noon, in 447 or 453. I'll probably stay much longer, but there is no guarantee -- you ask tomorrow by email before coming.

Past infos

The exam max score is 50 points. Students with low scores from Tests may take a chance of being scored at exam=65 points (with zeroing their tests score). The decision has to be made BEFORE taking the exam.
A homework 2 is due on 05 Jan 2004 (at the lecture).
The "Test II" on 12 Jan 2004 required your knowledge of:

• z-transform
• instantaneous spectrum
• filters description and design
• signal filtering theory
• window function basics

• DT signals
• LTI systems
• convolution
• FT, DFT, FFT of DT signals
• difference equations (basics from the 03 Nov lecture, no z-transform yet)

A free textbook covering some of the subjects can be found here: http://www.dspguide.com/pdfbook.htm
Local mirror:  http://www.ise.pw.edu.pl/dydaktyka/tra/dsp_book
The book, as far as I've "investigated" superficially, can be valuable -- at least as a quick reference.

Please remember:

• there are notation differences between lecture and "dspguide"
• The official book is Oppenheim & Schafer (though notation is sometimes different too)
• 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).
