Return to RF Cafe Quiz #13


1. a) Right-hand rule.

See this RF Cafe Labs experiment that proves the claim.



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