There is a good reason why Harold
Glenn called this an "Elementary Radio Quiz." It appeared in a 1947 issue of
Radio-Craft magazine. If you have been in the analog and RF electronics field
for more than a couple years and don't score 100%, it has to be due to a misreading
of accidental selecting of the wrong answer. I know what you're thinking - "The
fool must have screwed up and missed at least one and is making excuses." Not this
time - although I don't deny it could have happened. Anyway, it might be a fun quiz
to pass out in the break room or maybe present it to a Ph.D. candidate during an
interview ;-) "Bonne chance!," as
Corporal
Louis LeBeau might say!.

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.
