Electronic Coupling Quiz

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.

A score of 80% is nothing to brag about, but at least I got all the easy ones right. A couple ones I guessed at based on how the circuit looks - like the 'gimmick' coupling. This quiz by Popular Electronics' quizmaster Robert P. Balin tests your knowledge of coupling circuits. If it had not been for studying for my Ham radio tests, I would not have recognized the gamma match circuit. Fewer and fewer people nowadays - at least as a percentage of those engaged in electronics - are familiar with the detailed level of design. Entire products can be designed nowadays using just integrated circuits and, usually, a little software code.

Electronic Coupling Quiz

By Robert P. Balin

Electronic Coupling Quiz, August 1973 Popular Electronics - RF CafeMany types of coupling circuits are employed in electronics to meet matching requirements in feedback networks and between amplifier stages. Others are used between amplifiers and speakers, transmission lines, or antennas. Test your knowledge of coupling circuits and devices by matching those shown in A-J with their names numbered 1 to 10 at the right.


The answers are below.










1.  Balun

2.  Direct coupling

3.  Emitter coupling

4.  Gamma coupling

5.  Gimmick, or capacitive, coupling

6.  Impedance coupling

7.  Link coupling

8.  RC coupling

9.  "Tickler," or inductive, coupling

10. Transformer coupling












Popular Electronics published many quizzes over the years - some really simple and others not so simple. Robert Balin created many of the quizzes. This is a listing of all I have posted thus far.

About RF Cafe

Kirt Blattenberger,

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 ...
