What is defined as the weakening of signal amplitude as the signal passes through a medium?

Show Suggested Answer Hide Answer
Suggested Answer: C

Attenuation:Describes the progressive loss of signal strength as it travels through a medium (like air, cables, walls). It's caused by factors like absorption, distance, and obstacles.

Other Phenomena:

Diffraction:Bending of waves around obstacles.

Reflection:Waves bouncing off surfaces.

**Scattering: ** Waves dispersing in multiple directions.

I practiced a similar question, and I think attenuation was the term used for weakening signals.

I’m a bit confused between attenuation and scattering. They both seem to involve signal changes.

I remember something about signal loss, and I think it relates to attenuation too.
