Drag and Drop Question Drag and drop the RF terms from the left onto the corresponding statements on the right. Answer:

The correct answer is receiver sensitivity; noise floor; reflection; absorption; signal-to-noise ratio. The correct arrangement maps each RF term to its defining characteristic: receiver sensitivity describes the minimum signal level a device can successfully detect; noise floor represents the baseline level of background RF interference/noise present in an environment; reflection

Explanation

The correct arrangement maps each RF term to its defining characteristic: receiver sensitivity describes the minimum signal level a device can successfully detect; noise floor represents the baseline level of background RF interference/noise present in an environment; reflection occurs when an RF signal bounces off a surface (like a wall or metal object); absorption is when materials (like walls, water, or the human body) absorb and attenuate RF energy rather than letting it pass through; and signal-to-noise ratio (SNR) is the comparison between the desired signal strength and the background noise level, determining overall signal quality. Each term has a precise technical definition that distinguishes it from the others in the context of wireless RF behavior.
