Q from A to Z 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."

SYSTEM REQUIREMENTS

• Windows 95 or higher Pentium II 333 MHz or faster 64 MB RAM CD-ROM drive
• sound card

PUBLISHER'S COMMENTS
This easy to navigate tutorial is designed for beginning wireless and RF engineers and those who wish to review the many forms of Q. No knowledge of higher math required; some familiarity with RF design and measurement terms helpful. This 50-minute course:

• allows you to move through each session at your own speed, requires no extra work books,
• provides you with testing methods for the key concepts taught.

NAVIGATING Q from A to Z
Navigation is similar to any computer-based information application. Clearly designated sections with an intuitive layout leave no frustrating distractions.

1. The CD-ROM can be started from any PC that has Windows 95 (or higher), at least 64 MB of RAM, a sound card and speakers.
2. The material may be accessed by either choosing to view the course start to finish, or by choosing individual pages of interest.
3. Once the course is started, no interaction is required. The course can be paused at any point, and can be viewed page by page like a book.
