What is amplitude?

• The number of complete waves (cycles) that occur in one second.

• The distance between the extremities of a signal’s oscillation

• The process of transposing intelligence onto a carrier wave.

• The length of one complete wave (or cycle)

What is frequency?

• The number of complete waves (cycles) that occur in one second.

• The distance between the extremities of a signal’s oscillation

• The process of transposing intelligence onto a carrier wave.

• The length of one complete wave (or cycle)

What is wavelength?

• The number of complete waves (cycles) that occur in one second.

• The distance between the extremities of a signal’s oscillation

• The process of transposing intelligence onto a carrier wave.

• The length of one complete wave (or cycle)

What is frequency modulation?

• The audio signal that contains the information intended for transmission.

• The intelligence modifies the carrier wave’s amplitude.

• The process of transposing intelligence onto a carrier wave.

• The intelligence modifies the carrier wave’s frequency

What is the following statement defining:

signals falling between 30MHz and 300MHz

• HF

• VHF

• LF

• UHF

What measures frequency?

• joules

• millibars

• amps

• hertz

What is the following statement defining:

The audio signal that contains the information intended for transmission.

• intelligence

• modulation

• transceiver

• attenuation

What is attenuation?

• The distance between the extremities of a signal’s oscillation

• The “weakening” of a signal as its amplitude reduces

• The process of transposing intelligence onto a carrier wave.

• A measurement of frequency

You've had a radio failure in flight and see a flashing red light, what does this mean?

• stop

• vacate the control zone

• give way to other traffic and continue circling

• aerodrome unsafe - do not land

You've had a radio failure in flight and see a flashing white light, what does this mean?

• notwithstanding previous instructions do not land

• land at aerodrome and proceed to apron

• return to starting point of aerodrome

• return for landing
