This instance of the course is given in Hangzhou, China, at Zhejiang University, for students from Lund University and Zhejiang University.
Credits: 7.5 ECTS credits (60 credits corresponds to one year full time studies).
Recommended prerequisites: Calculus in one variable.
Assessments: Laboratory work, homework and a written exam.
Course coordinators: Benny Lövström (benny.lovstrom@bth.se)
Introduction
Welcome to the course in Digital Signal Processing. The course during the autumn 2013 will be held by Benny Lövström (benny.lovstrom@bth.se), Ronnie Lövström (ronnie@bems.se) and Jiandan Chen (chenjiandan@gmail.com). The course was given first time during autumn 2009 for the students following the China line at LTH, Lund University.
Schedule 2013
Lectures: 20 h.
Problem solving sessions: 20 h.
Laboratory work including homework: 14 h.
Aim
Every day we use gadgets in which the signals are stored and treated digitally. From the basic signal processing used in CD-players to advanced processing used in MP3 coding of music, speech coding in GSM, digital video and image processing. The course gives the basic knowledge in digital signal processing and knowledge of signal properties in the time domain as well as in the frequency domain. The course presents the fundamentals on digital signal processing such as fourier transform of analogous signals, fourier transform of discrete time signals, the discrete fourier transform (DFT), z-transform and input-output relations.
Contents
The course deals with time discrete signals and systems. Items such as the Fourier Transform, the Discrete Fourier Transform (DFT) and the z-transformed are treated in the course as well as some basic structures for implementation of digital filters. Also, system function and frequency functions are introduced as well as digital filters. Digital processing of analogous signals using A/D and D/A conversion are studied. In the laboratory work, practical applications of digital signal processing such as speech signal processing and biomedical signals processing are treated. Also, basic filter design using MATLAB is covered in the course.Literature

Problem solving sessions
Schedule for the problem solving lessons will be distributed on the home page at course start. The problems are mainly from the textbook and problems with solutions will be distributed to the students.
Examination
The examination consists of a final exam combined with homework during the course. The homeworks are compulsory and passed homeworks give extra marks (max 1 mark) which will be added to the result from the final exam (valid for one year). The final exam consists of 5 problems. Each problem will give maximum 1 mark.
To pass the course, you must pass the final exam and fulfill the laboratory works including the homework.
Limits:
0.0-2.9
not passed
3.0-3.9
gives grade 3
4.0-4.9
gives grade 4
>5.0
gives grade 5
Home works: Home works are included in the course and are compulsory. The aim of the home works is to
· A: get a continuous learning process.
· B: give feedback to the students.
All problems in the homeworks must be solved individually but the students may ask the teachers for help if they get any problems. The home works will be returned with comments and perhaps corrections. Then you have to add the corrections to your solutions.
