General Knowledge
Answers to RF Cafe Quiz #13

RF Engineering Quizzes - RF Cafe WebsiteAll RF Cafe Quizzes make great fodder for employment interviews for technicians or engineers - particularly those who are fresh out of school or are relatively new to the work world. Come to think of it, they would make equally excellent study material for the same persons who are going to be interviewed for a job. Good luck!

A complete list of RF Cafe Quizzes.

1. a) Right-hand rule.

See this RF Cafe Labs experiment that proves the claim.

2. b) Lissajous waveform (lē'-su-zhOO").

 Lissajous pattern on o-scope

Named after Jules Antoine Lissajous.

3. b) frā-nĕl'  -  that's right, it is NOT pronounced frĕz-nĕl'

4. a) Lowpass

Low frequencies easily pass through the series inductors and do not pass through the shunt capacitors.

5. b) 4

Each reactive component (2 inductors + 2 capacitors) creates a pole in the transfer function.

6. c) Microstrip

Microstrip uses a conductor running over top of a ground plane, with a dielectric in-between.

7. b) 90° H-Plane bend

The mnemonic used for waveguide is that an E-Plane bend curves along the narrow side (the "E"asy bend), and that a H-Plane bend curves along the wide side (the "H"ard bend). There is no such thing as a Maxwell bend.

8. c)  62 kΩ, ±10% = 3 (62 x 103 = 62 kΩ), Silver = ±10%

9. a) Tin whiskers

10. b)

RF Cafe -

Quizzes from vintage electronics magazines (and many custom RF Cafe-generated quizzes) such as Popular Electronics, Electronics-World, QST, Radio-Electronics, 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.

About the RF Cafe™ Website ©1996-2026

Kirt Blattenberger - RF Cafe WebmasterRF 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 lady's voice announced "You've Got Mail" when a new message arrived...
