What is one advantage of digital signals over analogue signals?

Digital signals have a clear advantage over analogue signals when it comes to handling interference, especially over longer distances. This is primarily due to the way digital signals represent information: they use discrete values, typically represented as binary data (0s and 1s).

As digital signals travel through various mediums, they are less susceptible to degradation caused by noise and interference. This means that even if a digital signal encounters interference, it can be processed and cleaned up, allowing for easier correction and restoration of the original signal. Most digital communication systems include error detection and correction mechanisms that can identify and rectify any errors that may have occurred during transmission.

In contrast, analogue signals represent information in a continuous wave format, making them more vulnerable to interference and distortion, which can significantly affect the quality and clarity of the transmitted information. This vulnerability can lead to a gradual degradation of the signal quality, especially over significant distances, ultimately making it harder to retrieve the original information without loss.

Therefore, the advantage of digital signals in terms of effectively managing interference and maintaining signal integrity over longer distances supports the assertion that they are superior in this area.
