Which of the following statements is true concerning signal degradation?

Signal degradation refers to the loss of signal quality and strength as it travels through a medium. It is a phenomenon affecting both analog and digital signals. In analog signals, degradation can manifest as noise interference, attenuation, or distortion, which adversely affects their quality and clarity. On the other hand, digital signals also experience degradation, primarily in the form of bit errors due to noise, interference, or insufficient signal strength.

This statement is particularly true because both types of signals are subjected to similar challenges as they traverse through various media, whether wired or wireless. The influence of environmental factors, such as weather conditions and physical obstructions, also plays a significant role in affecting signal integrity in both formats. By recognizing that degradation occurs in both analog and digital signals, we can better design systems and protocols to mitigate these issues effectively.

Other options incorrectly suggest that degradation is limited to only digital signals, that it can be entirely eliminated, or that it is exclusively an issue for wired connections. In reality, signal degradation is a natural aspect of communication systems encountered in a wide range of scenarios.
