Electronic Alphabet Quiz

May 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 "Electronic Alphabet Quiz" from a 1963 issue of Popular Electronics magazine is a bit trickier than others because it requires you to think abstractly rather than concretely. Quiz-maker Robert Balin presents a series of circuits and components along with the first letters of the related topics. Your mission, should you decide to accept, is to match the item to the letter. The example provided is matching the letter "J" to a drawing of that type of half-wave antenna. I have to admit that my attempt at matching all of the items and letters was taking a lot of time, so I quit before finishing all of them; my hard head is better at concrete thinking.

Electronic Alphabet Quiz

By Robert P. Balin

The letters of the alphabet are often used as abbreviations for electronic terms. Thus, J means to the electronics enthusiast a type of half-wave antenna. Can you match the letters below with the drawings (1-10) of the devices and circuits to which they most logically refer?

Quizzes from vintage electronics magazines such as Popular Electronics, Electronics-World, QST, Radio-Electronics, 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.

Alphabet Quiz Answers

A - 8  Class A amplifiers use a biasing level which permits plate current to flow continuously when an a.c. signal is applied to the grid.

B - 3  The B battery is used to supply the plate voltage for battery-operated tubes.

C - 9  Operating temperatures for electronic devices are often given in degrees Celsius (°C), formerly known as the centigrade scale.

E - 7  The E layer of the ionosphere 50 - 90 miles up provides daytime over-the-horizon short-wave radio reception.

L - 10  An L section choke input filter is used in full-wave, high-current power supplies such as those employing mercury vapor rectifiers.

Q - 1  The Q of a coil is a figure of merit representing the ratio of its reactance to resistance at a specific frequency.

S - 5  An S-meter is a relative signal strength indicator on radio receivers, calibrated in "S" units from 0 - 9,          and in db above S-9.

X - 2  X-ray radiation is produced in a Roentgen tube when a high-velocity electron beam strikes a tungsten target.

Y - 6  The Y connection of transformer secondary windings provides three-phase power in which the line-to-line voltage equals 1.732 times the line-to-ground voltage.

Z - 4  The Z-axis input of an oscilloscope permits intensity modulation of the electron beam by applying the           signal to the grid-cathode circuit.

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 lady's voice announced "You've Got Mail" when a new message arrived...
