Course Syllabus

Week Topic
Week 1 What is a filter? Why and in which applications are filters needed? Linear filtering concepts: Representation of periodic/non-periodic analog signals with Fourier series/integrals. Filter response in time/frequency-domain. Gain and phase response representations.
Week 2 Filter types: Low-pass (LP), high-pass (HP), band-pass (BP), band-reject (notch) (BR), all-pass (AP). Passive filters (RC, RLC) and their time/frequency-domain responses. Requirement for active filters. Definition of “active device”. OpAmp as an active device. Schemes for analog filter realization: Continuous-time/Discrete-time, Active-RC, Gm-C, switched-capacitor, digital filter, etc.
Week 3 Filter specifications: Passband ripple, passband corner frequency, stopband corner frequency, max. pass-band gain, min. stopband attenuation, group delay, transition band steepness, filter order.
Week 4 Determining a nominal filter transfer function: Butterworth, Chebyshev.
Week 5 Determining a nominal filter transfer function (...contd) : Cauer (elliptic), Bessel, inverse Chebyshev. Frequency transformations (converting LP transfer function to HP, BP or BR)
Week 6 First-order and biquadratic filter realizations: Realizing real poles/zeros. Types of biquads: Sallen-Key biquad.
Week 7 Cascading first/second-order filters for high-order filter design.
