LICENSE QUIZ #247

de Steve, AE8AT

Coming home from a backpacking trip, I had time to think about the weather. My nighttime lows were “forecast” to be in the mid-50’s (around 12°C). When I woke up every hour because “actual” was mid-60’s and humid, I had many opportunities where I was longing for cooler weather. So the quiz topic this week is anything polar!


T3A09 Which of the following results from the fact that signals propagated by the ionosphere are elliptically polarized?

A. Digital modes are unusable

B. Either vertically or horizontally polarized antennas may be used for transmission or reception

C. FM voice is unusable

D. Both the transmitting and receiving antennas must be of the same polarization


G6A07 What are the operating points for a bipolar transistor used as a switch?

A. Saturation and cutoff

B. The active region (between cutoff and saturation)

C. Peak and valley current points

D. Enhancement and depletion modes


E5C02 How are impedances described in polar coordinates?
