(9 cards)
1
Q
What is a Cycle?
A
One positive and one negative iteration of a wave representing a full 360°
2
Q
What is a Period?
A
Time it takes for a wave to complete one cycle. Measured in seconds.
3
Q
What is Frequency?
A
Number of cycles per second. Measured in Hertz.
4
Q
What is Phase?
A
A particular point in the cycle of a waveform. Measured in degrees.
5
Q
What is Wavelength?
A
The distance of one cycle, measured at the beginning and end of the Waveform.
6
Q
What is Amplitude?
A
Value of the power of a sine wave. Measured in decibels.
7
Q
What is Signal Propagation?
A
How an EM wave travels through a medium
8
Q
What is Free Space Loss?
A
Power loss due to spreading of the wave’s energy
9
Q
What is Polarization?
A
The direction of an EW’s E-field in reference to the earth’s surface.
