Fridays are good days for
Carl
and Jerry stories,
Mac's
Electronics Service Shop sagas, Hobnobbing
with Harbaugh, electronics-themed comics, electronics quizzes, and other forms of
nerd entertainment. Here is another of Robert P. Balin's great challenges titled,
"Diagram Quiz." Most RF Cafe visitors will easily identify eight or nine of the ten diagrams.
Relatively few will be familiar with the Rieke diagram (hint: power amplifier designers
will know about it). The Biasing diagram is a bit misnamed IMHO, and could cause
confusion. Bon chance.
Electronics Diagram Quiz
By Robert P. Balin
Most electronic technicians work with schematic diagrams, wiring diagrams, and block
diagrams on a routine basis, and are familiar with all symbologies used. But how many
have heard of a Nyquist or a Venn diagram? See if you can correctly identify the diagrams
shown here by matching their names (1-10) with the actual drawings (A-J). Consider yourself
fairly knowledgeable if you can identify six or more. But you could still be a crackerjack
technician if you match no more than four.
1 Basing __
2 Chromaticity __
3 Circle __
4 Directivity __
5 Energy level __
6 Logic flow __
7 Nyquist __
8 Rieke __
9 Venn __
10 Winding __
         
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.

Diagram Quiz Answers
1 - E A Basing diagram (also called outline drawing) shows the location
of, and identifies the pins of, a vacuum tube or solid-state device.
2 - G A Chromaticity diagram displays the various spectral colors that
can be reproduced in our color TV system by using the standard wavelengths of red, green,
and blue primaries. From it we can see the range of hues and saturation of the colors
with respect to white.
3 - I A Circle diagram is used to determine the input impedance of a transmission
line, in terms of its electrical length and load impedance. The solution is displayed
graphically.
4 - F A Directivity diagram (also called polar diagram) is a plot of the
directional characteristics which enable an antenna to radiate or receive more energy
in some directions than in others.
5 - D An Energy Level diagram shows the increases and decreases of electric
power as current intensities rise and fall along a channel of signal communications.
6 - J A Logic Flow diagram provides a graphical representation of a computer
program or routine at various stages during an operation.
7 - A A Nyquist diagram is used to evaluate the stability of feedback
systems over a wide range of operating frequencies.
8 - B A Rieke diagram is used to evaluate the performance of microwave
oscillators such as klystrons and magnetrons. Contours of constant power output and frequency
are plotted on a diagram in which the circles represent the SWR, and the axial lines
the phase angle of the load.
9 - H A Venn diagram shows the relationship between two independent variables,
A and B. The diagram is of assistance in visualizing logic operations.
10 - C A Winding diagram for an alternating current machine shows the phase and polar
relationships of the windings of a multiphase generator, and provides a means of connecting
several groups together to obtain a desired output.
