Unlike most books on filters, Analog and Digital Filter Design does not start from a position of mathematical complexity. It is written to show readers how to design effective and working electronic filters. The background information and equations from the first edition have been moved into an appendix to allow easier flow of the text while still providing the information for those who are interested.

The addition of questions at the end of each chapter as well as electronic simulation tools has allowed for a more practical, user-friendly text.

Key Features

Provides a practical design guide to both analog and digital electronic filters Includes electronic simulation tools *Keeps heavy mathematics to a minimum


Engineers in RF, Audio and other analog and digital communications circuit design, test & measurement, and production environments

About the Author

Steve Winder

Steve Winder specializes in designing circuits for telecommunications applications, but has experience in a number of fields. As the current European Applications Engineer for Supertex Inc. Steve works alongside design engineers throughout Europe to design circuits using components made by Supertex, a U.S. based manufacturer of high voltage MOSFETs, CMOS integrated circuits and ASICs. Prior to joining Supertex, Steve was for many years a team leader for a group of analogue and digital design engineers at British Telecom's research and development laboratories, now known as Adastral Park, based near Ipswich, UK. Here, Steve applied his analytical skills to many technical areas but specialized in wideband analogue and digital transmission systems using copper pairs and optical fibre. In this role, Steve's strength was in radio frequency design, low-power design, low-noise design and systems engineering.
