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 Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

People old and young enjoy waxing nostalgic about and learning some of the history of early electronics. Popular Electronics was published from October 1954 through April 1985. All copyrights are hereby acknowledged. See all articles from Popular Electronics.
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.
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).
