Book description

Simplified Design of Filter Circuits, the eighth book in this popular series, is a step-by-step guide to designing filters using off-the-shelf ICs. The book starts with the basic operating principles of filters and common applications, then moves on to describe how to design circuits by using and modifying chips available on the market today. Lenk's emphasis is on practical, simplified approaches to solving design problems.
  • Contains practical designs using off-the-shelf ICs
  • Straightforward, no-nonsense approach
  • Highly illustrated with manufacturer's data sheets
