Q from A to Z is the first of three CDs in the Filter Techniques Set and explains the concept of Q and how it can be applied to understanding the relationship between loss and bandwidth in filters, the design of oscillators with improved stability and phase noise, and the best possible match for a given bandwidth and load characteristics. The course includes sample problems and solutions, a bibliography of source materials, web links, and the complete text of Randy Rhea's reference article, "Multimode High-Frequency Inductor Model."
