Course Description

This course is optional courses designed for Engineering Master of Computer Science in TIEI. It will systematically describe how to process the signal in a digital way. The basic theories and methods of Digital Signal Processing will be introduced. Emphasis will be given to the key points, such as the discrete signal and system, digital filter design, discrete Fourier transform and its fast algorithm. Besides, some experimental projects will be combined to cultivate students’ ability of analysis and design. Through learning of this course, students need to master the principles, general techniques and methods about using the digital methods to process deterministic signal, laying a solid theoretical foundation for the analysis and processing methods of random signals and multidimensional signals. At the same time, students should understand the realization and application fields of the digital signal processing.
