This week's crossword puzzle has an RF System Analysis theme. Most of the longer words are terms you will find in cascade calculators such as Wireless System Designer. Avid cruciverbalists amongst us appreciate that each week I create a new crossword puzzle that has a theme related to engineering, mathematics, chemistry, physics, and other technical words. You will never be asked the name of a movie star unless he/she was involved in a technical endeavor (e.g., Hedy Lamarr). Enjoy!
