What occurs when comparing receivers of different sensitivity?

• A. The more sensitive receiver produces more noise
• B. The less sensitive receiver produces less signal or more noise
• C. Both receive the same signals
• D. Both receivers become equally sensitive

Answer: (B)

When comparing receivers of different sensitivity, it's important to understand how sensitivity impacts their performance in receiving signals. The less sensitive receiver produces less signal or more noise because it is not able to detect weaker signals effectively. Sensitivity is defined as the receiver's ability to convert an incoming signal into a usable output; a sensitive receiver will pick up faint signals that a less sensitive receiver might miss entirely. As a result, the less sensitive receiver tends to struggle with weaker signals, and while it may pick up some noise, the lack of sensitivity means it often fails to provide a clear, distinguishable output from those weak signals. This translates to a poorer signal-to-noise ratio and can lead to a greater perception of noise, as the less sensitive device may amplify background interference that would have been filtered out by a more sensitive receiver. Thus, the accurate understanding of sensitivity explains why the less sensitive receiver would have issues with both signal detection and the clarity of reception, resulting in less signal and potentially more background noise.
