May 1963 Popular Electronics
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

This quiz from Popular Electronics 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?

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
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.
