Describes the selection of cores, capacitors, mechanical shapes, and styles for the timeliest design, construction, and testing of filters-analyzing matrices of various filter types based on close approximations, observation, and trial and error. Offers simple methods of measuring AC and DC power lines. with illustrations
READERSHIP: Electrical and electronics, power supply design, systems, and radio and telecommunications engineers, and upper-level undergraduate and graduate students in these disciplines.

Simple parameters and techniques for creating manufacturable, repeatable products:

reveals up-to-date insights into the cause and eliminaton of common mode noise in lines and equipment; covers resistive, transformer, switcher, and UPS load; examines lossey components and ratiated emissions; discusses benefits and limitations of Pl, T, L, dissipative, cauer, commercial, and conventional filters; compares and contrasts 50 and 60 Hz filters with 400 Hz; gives matrix transfer functions for various filters; details capacitor specifications, construction, and self-resonant frequency; summarizes isolation, leakage current, skin effect, and voltage translation; explores new data on spike, pulse, trapezoid, and quasisquare waves; evaluates the input and output impedance for differential mode and DC filters; reviews the latest high-current filters
