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)
