Which term describes the ability of a receiver to discriminate between multiple signals?

• A. Discrimination ratio
• B. Sensitivity
• C. Selectivity
• D. Harmonic distortion

Answer: (C)

The term that describes the ability of a receiver to discriminate between multiple signals is selectivity. Selectivity refers to a receiver's ability to isolate and process a specific signal of interest from other signals that are operating at the same or similar frequencies. High selectivity allows a receiver to effectively differentiate between closely spaced channels or signals, ensuring that it can receive the intended transmission without interference from neighboring transmissions. In contrast, sensitivity relates to the minimum signal strength that a receiver can detect; this does not directly imply discrimination between signals. The discrimination ratio, while important in evaluating the quality of a receiver, typically refers to the ability to differentiate between the desired signal and unwanted noise or interference rather than between multiple signals directly. Harmonic distortion generally pertains to the distortion of a signal caused by the nonlinearities in the system and is not associated with the receiver's ability to discriminate between signals.
