Course Objective: The objective of the course Filter Design is to equip students with the theoretical knowledge and practical skills required to analyze, design, and implement various types of analog and digital filters. The course emphasizes filter approximation techniques, frequency response shaping, pole-zero analysis, and the application of filters in signal processing, with a focus on Butterworth, Chebyshev, Inverse Chebyshev, and Cauer designs, as well as switched capacitor filters used in modern electronic systems.
After completion of the course student will be able to:
| COs | CO Statement | BL |
|---|---|---|
| CO1 | Choose an appropriate transform for the given signal. | K2 |
| CO2 | Choose appropriate decimation and interpolation factors for high performance filters. | K2 |
| CO3 | Model and design an AR system. | K3 |
| CO4 | Implement filter algorithms on a given DSP processor platform. | K3 |
| CO5 | Design and analyze Chebyshev, Inverse Chebyshev, and Cauer filters based on frequency specifications using rational functions and pole-zero locations. | K4 |
