Beskrivelse:
Filters is a complete course in designing active and passive filters. It is split into 3 sections: Revision which provides underpinning knowledge required for those who need to design filters. Filter Basics which is a course in terminology and filter characterization, important classes of filter fundamental mathematics, filter order impedance and impedance matching, and effects of different filter types. Filter Design which includes virtual laboratories that guide users through basic requirements capture and filter synthesis to simulation and E12 normalization for a range of both passive and active filters. Filter Design includes a suite of filter synthesis and simulation tools.

Explanation of filter design theory
Interactive laboratories to assist conceptual understanding
Expert systems for active and passive filter design
SPICE simulation of all filter circuits
E12 normalisation capability
