Paperback. Condición: New. Print on Demand. This book presents a systematic method to design uniform and composite electric wave-filters. It provides the theoretical foundation, develops design formulas, and presents practical design procedures. The author thoroughly describes the ladder type of recurrent network, showing how its elements determine its transmission and attenuation characteristics, and impedance. The book explores the concept of constant k wave-filters having any preassigned transmitting and attenuating bands and demonstrates how to derive general wave-filters with adjustable propagation constants. It also introduces the theory of composite wave-filters constructed by combining uniform filter sections with equivalent characteristic impedances but different propagation constants. The book combines a solid theoretical foundation with practical design guidance, making it invaluable to engineers working in wave-filter design and development.
