This course provides basic knowledge in analog filter design. It will include:
1) synthesis of filter transfer function
2) basic active filter components
3) active-RC filter design and simulation
Note that this course is only available in a face-to-face classes.
Due to the limitation of workstations, the number of student will be limited to 8. The students will be selected based on students skill and motivation.
Students who wish to take this course should contact the lecturer in advance (see the contact address bellow).

This course aims to make the students understand the basic function of analog filters as well as design steps in active filter
implementations.
- Students can derive the transfer function of first and second order low-pass filters for a given specification
- Students can use frequency transformation technique to derive various type filters from a prototype low-pass filter
- Student can design an active-RC filter based on a given specification
- Student can verify the filter's frequency characteristic using simulator
