What is indicated by the ability of a receiver to maintain performance under multiple signal conditions?

• A. Stability
• B. Robustness
• C. Intermodulation
• D. Selectivity

Answer: (D)

The ability of a receiver to maintain performance under multiple signal conditions is best described as selectivity. Selectivity refers to the receiver's capacity to differentiate between multiple signals within a given frequency range, allowing it to isolate and amplify the desired signal while minimizing interference from others. This characteristic is crucial in environments where numerous signals may be present, as it ensures clear communication by effectively filtering out unwanted noise and co-channel interference. Stability typically describes the consistency of a receiver’s frequency and performance under varying conditions but does not specifically relate to handling multiple signals. Robustness generally refers to the durability and reliability of the equipment in terms of its physical and operational resilience, rather than its performance in congested signal environments. Intermodulation involves the mixing of signals within the receiver, which can generate unwanted frequencies but does not address the ability to maintain performance amidst multiple signals directly. Thus, selectivity is the most appropriate term that captures how well a receiver operates amidst varying signal conditions.
