Electronic "A" Quiz

Wax nostalgic about and learn from the history of early electronics. See articles from Popular Electronics, published October 1954 - April 1985. All copyrights are hereby acknowledged.

Here is an Electronic "A" Quiz for you to test your knowledge of terms, compliments of Popular Electronics quizmeister Robert P. Balin. The number of spaces is equal to the number of characters needed in addition to the leading "A" to spell the word. About half of them are easily identified, but the others might take some head scratching - particularly numbers one and four (hint: four has to do with vacuum tubes). Number seven's illustration could be better, so don't feel bad if you don't get it (I didn't), because it is a phenomenon only seen on cathode ray tube (CRT) displays, not on LCDs. The word "amplifier" fits for number eight, but that is not the answer sought. My score with only a couple minutes of consideration was a paltry 6:10.

Electronic "A" Quiz, April 1968 Popular Electronics - RF CafeBy Robert P. Balin

Electronic technicians and hobbyists must learn the meaning of many technical terms related to their work. Illustrated below are 10 such terms having nothing in common except that they all begin with the letter "A." Test your knowledge of electronic terminology by filling in the missing letters.

 

See answers below.


Quizzes from vintage electronics magazines such as Popular Electronics, Electronics-World, QST, and Radio News were published over the years - some really simple and others not so simple. Robert P. Balin created most of the quizzes for Popular Electronics. This is a listing of all I have posted thus far.

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...
