    digital filter
  • In electronics, computer science and mathematics, a digital filter is a system that performs mathematical operations on a sampled, discrete-time signal to reduce or enhance certain aspects of that signal.
  • (Digital Filtering) A feature found on may newer spectrometers which eliminates wraparound artifacts by filtering out the higher frequency components in the time domain spectrum. [Chapter 7]
  • (Digital filters) Filters reduce the influence of draft or vibration, enabling the balance to display a stable reading faster.
    design
  • Do or plan (something) with a specific purpose or intention in mind
  • an arrangement scheme; "the awkward design of the keyboard made operation difficult"; "it was an excellent design for living"; "a plan for seating guests"
  • the act of working out the form of something (as by making a sketch or outline or plan); "he contributed to the design of a new instrument"
  • Decide upon the look and functioning of (a building, garment, or other object), typically by making a detailed drawing of it
  • plan: make or work out a plan for; devise; "They contrived to murder their boss"; "design a new sales strategy"; "plan an attack"

Digital Filter Design Solutions (Artech House Microwave Library)
Digital electronic filters are becoming a key technology in a growing number of products used in industries as diverse as medicine, meteorology, finance, optics, and telecommunications. Not all developers in these varied fields have the electrical engineering expertise or the time required for selecting just the right digital filter for new product development. This book and CD-ROM package offers instant practical digital filter knowledge and supplies designers and developers with a toolkit of more than 250 pre-designed filters (on the CD-ROM) that they can use immediately. Digital Filter Design Solutions allows practitioners to quickly compare filters and select the ones that deliver optimal performance for their projects. With an extensive range of filters ready for the developer's choosing, this unique toolkit speeds up development time, allowing new products to be quickly brought to market. Moreover, by enabling developers to better select filters, this book helps improve product quality and user satisfaction. CD-ROM Included! Complementing the book, this highly valuable disc contains an archive of filter coefficients and design functions written in Matlab[registered]. These are the essential tools professionals need to handle their projects with speed and confidence.

Analog and Digital Filter Design, Second Edition (EDN Series for Design Engineers)
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.


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