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.

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.

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...
