Continuous Time Active Analog Filters

Discover the techniques of analog filter designs and their utilization in a large number of practical applications such as audio/video signal processing, biomedical instrumentation and antialiasing/reconstruction filters. Covering high frequency filter design like active R and active C filters, the author tries to present the subject in a simpler way as a base material for analog filter designs, as well as for advanced study of continuous-time filter designs, and allied filter design areas of current-mode (CM) and switched capacitor filters. With updated basic analog filter design approaches, the book will provide a better choice to select appropriate design technique for a specific application. Focussing mainly on continuous time domain techniques, which forms the base of all other techniques, this is an essential reading for undergraduate students. Numerous solved examples, practical applications and case studies on audio/video devices, medical instrumentation, control and antialiasing/reconstruction filters will provide ample motivation to readers.
