What term refers to an increase in wave amplitude?

• A. Carrier Wave
• B. Antenna Gain
• C. Radio Frequency Interference
• D. Wave Propagation

Answer: (B)

The concept here is how the signal strength can be increased in a given direction. Antenna gain describes how much an antenna concentrates energy in its main direction compared with an ideal isotropic radiator. When gain is higher, the electric field, and thus the amplitude of the wave in that direction, is stronger. It’s this focus of power that effectively raises the observed amplitude in the targeted direction. The other terms don’t describe an increase in amplitude: the carrier wave is the basic oscillation that carries information, interference is unwanted noise, and wave propagation is the movement of the wave through space.
