EMI Filter Design, 2nd ed.

Richard Lee (OZ) Ozenbaugh


350 pages

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
