Robert P. Balin created
many electronics-related quizzes for
Popular Electronics. I have posted many of them here on RF
Cafe, and will post more in the future. Most of the Popular Electronics quizzes
were pretty easy for anyone who has been in the electronics realm for a few years.
This quiz, by contrast, is a real head scratcher. I was only able to get two out
of 10 answers correct. It would take someone who is a physics historian to
even come close to acing it - or I'm really just lacking in knowledge. Good luck.
Co-Inventors Quiz
By Robert P. Balin
Many important discoveries and inventions in the field of electronics were made
by men who worked together as a team, and current textbooks still include the names
of the co-inventors (1-10) listed below, See how many of these teams you can match
with the sketches (A-J) which illustrate the devices or theory which they helped
to develop.
(See answers below)
1.Barkhausen-Kurz ____
2. Biot-Savart
____
3. Eccles-Jordan ____
4. Fermi-Dirac ____
5. Fletcher-Munson ____
6. Foster-Seeley ____
7.
Geiger-Muller ____
8. Kennelly-Heaviside ____
9. Langmuir-Child
____
10. Loftin-White ____
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.

Answers
1-D. The Barkhausen-Kurz oscillator circuit is a positive-grid u.h.f.
oscillator by Lecher wires in the grid and plate circuits.
2-E. The Biot-Savart Law, or Ampere's Law, specifies the direction
and magnitude of the magnetic field at any point in the vicinity of a current-carrying
conduelor.
3-J. The Eccles-Jordan trigger circuit, or flip-flop, is a bistable
multivibrator in which the conducting state of each half is changed only by the
incoming pulses.
4-B. Fermi-Dirac statistics predict the availability of current carriers
in the semiconductor materials used to make transistors.
55-I. Fletcher-Munson curves show the relationship between
the signal frequency and the sound intensity required by a listener to hear a constant
loudness.
6-G. The Foster-Seeley FM discriminator circuit converts a frequency-modulated
radio-frequency carrier into an
amplitude-modulated signal from which the audio is detected by a balanced diode
circuit.
7-F. A Geiger-Muller tube detects nuclear radiation when beta particles
ionize the gas inside the tube to start a discharge of electrons between the cathode
case and highly positive anode.
8-C. The Kennelly-Heaviside layer is the original term for the ionosphere,
now known to consist of various layers, whose height and degree of ionization determine
their effect upon high-frequency radio transmission.
9-H. The Langmuir-Child Law, or Three-Halves Power Law, describes
the relationship between the applied voltage and the resulting current in a diode
vacuum tube.
10-A. The Loftin-White amplifier circuit uses direct coupling between stages
and can handle signal frequencies down to d.c.
