Electronic Curves Quiz
February 1963 Popular Electronics

February 1963 Popular Electronics

February 1963 Popular Electronics Cover - RF CafeTable of Contents

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.

This Electronics Curves Quiz will probably prove to be a little more of a challenge than some of the ones previously appearing in Popular Electronics magazine. Being a rocket scientist won't help you much here, but being a seasoned electronics technician, hobbyist, or engineer will sure come in handy. Be careful to note the axis unit labels - I got tripped up by that from being lazy and missed one. Surely you won't be hindered by such an oversight.

Electronic Curves Quiz

By Robert P. Balin

The operation of electronic devices and circuits is often represented by characteristic curves. See if you can match the electronic devices and circuits at left (1 - 10) with their corresponding curves (A - J).

 

Electronic Curves Quiz, February 1963 Popular Electronics - RF Cafe

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...
