Filter Theory and Design is a level 2 course which follows the prerequisite course Eng201 (Linear System Analysis and Design). It addresses basic knowledge of system analysis and modeling, the theory of filters and design techniques for analog and digital filters based on the theories of signals and systems introduced in course Eng201. Filters are essential components which are extensively used in various electronic systems. Comprehension and mastery of filter theories will be necessary to achieve expected performance in electronic system design. This course also serves as the prerequisite for other coursework in the areas of signal processing and communications engineering. This course is to provide a theoretical foundation and some practical experience for analog and digital filters design in electronic systems and signal processing techniques.
