Active Filters

Using an accessible yet rigorous approach Active Filters: Theory and Design highlights the essential role of filters especially analog active filters in applications for seismology brainwave research speech and hearing studies and other medical electronics. The book demonstrates how to design filters capable of meeting a given set of specifications.Recognizing that circuit simulation by computer has become an indispensable verification tool both in analysis and in design the author emphasizes the use of MicroCap for rapid test of the filter. He uses three basic filter types throughout the book: Butterworth Chenyshev and Bessel. These three types of filters are implemented with the Sallen-Key infinite gain multiple feedback state-variable and biquad circuits that yield low-pass high-pass band-pass and band-reject circuits. The book illustrates many examples of low-pass high-pass band-pass and notch active filters in complete detail including frequency normalizing and denormalizing techniques.Design equations in each chapter provide students with a thorough grounding in how to implement designs. This detailed theoretical treatment gives you the tools to teach your students how to master filter design and analysis.
