COURSE NAME
● Signals and Systems (Undergraduate EEE2008 Class)
LECTURER
● Professor Joong Kyu Kim(Rm#: 21225, Tel: 0312907122)
COURSE OBJECTIVE
● To learn basic techniques on how to analyze signals and systems in both time and frequency domains for continuous as well as discrete cases.
COURSE DESCRIPTION
● Fundamentals of the analysis and processing of continuous and discrete signals. Linear systems and filtering. Convolution, Fourier Series(FS), Fourier Transform(FT), Discrete Time Fourier Transform(DTFT), Discrete Fourier Transform(DFT), and Sampling Theorem are discussed in detail. Analog and digital communication system and Fast Fourier Transform(FFT) will also be briefly introduced. PC based simulation and data processing are used to demonstrate the above concepts.
TEXTBOOK
● There is no particular textbook for this class, but the Signals and Systems by Haykin & Van Veen (Wiley) will be used as the main reference.
