About RF Cafe
Copyright: 1996 - 2024 Web BSEE - KB3UON RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived... All trademarks, copyrights, patents, and other rights of ownership to images

Acoustics Anagram
|
|
Isn't an anagram a word game where letters of one word are rearranged to spell another word or series of words? For instance, an anagram for 'microwave' is 'warm voice,' one for ''resistance" is "ancestries," and for "vector" is "covert." If so, then this puzzle is misnamed; it is really a crossword puzzle. Maybe back in 1961 the word anagram included this type of puzzle. Regardless of the naming error, I did learn a new word: "inertance," which means "the effect of inertia in an acoustic system, an impeding of the transmission of sound through the system."
