Accessible yet rigorous, 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. Recognizing that circuit simulation by computer has become an indispensable verification tool both in analysis and in design, this book emphasizes the use of MicroCap for rapid test of the filter. Numerous examples of low-pass, high-pass, band-pass, and notch active filters are illustrated in complete detail, including normalizing and denormalizing techniques.
