ECET 4320:Active Filters

3 Credit Hours
Prerequisite: ECET 2310, and ECET 2310L Corequisite: ECET 4320L
This course is a study of the characteristics, analysis, and practical topologies of active filters. The state-variable Sallen-Key topologies are emphasized. Popular filter responses including Butterworth, Chebyshev, Bessel, and Cauer (elliptic) are studied. Delay sensitivity, frequency scaling, impedance scaling, determination of pole-zero locations, and transfer function transformations are studied. Filter synthesis techniques are presented. An introduction to switched-capacitor and digital filters is also included.
