When intending to build electronic filters, young engineers should be aware of the fundamental principles while not getting bogged down in intricate and elaborate mathematical aspects. A presentation of the basic principles supplemented by numerical programs illustrating the design technique will fulfil these requirements.There is not much by way of competition in this area. Much of the existing competition is older and does not include many of the newer ideas present in this book, such as current mode filters.

Rabindranath Raut obtained his M.Tech. degree in radiophysics and electronics from the University of Kolkata, India, in 1968, and his Ph.D. degree in electrical engineering from Concordia University, Montreal, Canada, in 1984. While in India, he worked as an electronics engineer (1968-1972) at the Indian Space Research Organization, and as a lecturer (1972-1978) in the Indian Institute of Technology. From 1983 to 1991, he worked as a senior radio-frequency electronic circuit and senior radio-frequency integrated circuit design engineer in various organizations in Canada. In 1991, Dr. Raut joined the faculty of the Electrical and Computer Engineering Department at Concordia University, where he still teaches. He has published numerous articles in various international journals and conference proceedings. He is a senior member of the IEEE (USA), and a licensed professional engineer in the provinces of Quebec (OIQ) and Ontario (PEO), Canada. Dr. Raut?s teaching and research interests lie in the areas of electronics and analog VLSI, with a specialization in analog filters and radio frequency circuits and systems.

M.N.S. Swamy received his Ph.D. degree in electrical engineering from the University of Saskatchewan, Canada, in 1963. He is presently a Research Professor and the Director of the Center for Signal Processing and Communications in the Department of Electrical and Computer Engineering at Concordia University, Montreal, Canada, where he served as the Founding Chair of the Department of Electrical Engineering from 1970 to 1977, and Dean of Engineering and Computer Science from 1977 to 1993. Since 2001, he has been holding the Concordia Research Chair in Signal Processing. Dr. Swamy has also taught in the Electrical Engineering Department of the Technical University of Nova Scotia, Halifax, and the University of Calgary, as well as in the Department of Mathematics at the University of Saskatchewan. He is the author or co-author of many articles and several books, and a Fellow of many societies including the IEEE , the IET (UK) and the EIC (Canada). He is the recipient of many awards including the IEEE-CAS Society education Medal, Golden Jubilee Medal, and the Guillemin-Cauer best paper award. He was the president of the CAS-Society in 2004 and Editor-in Chief of the IEEE transactions on Circuits and Systems during 1999-2001. Recently, he was awarded the title of Honorary Professor by the National Chiao Tung University, Taiwan.
