What is a risk of using analog signals in comparison to digital signals?

Using analog signals often entails a greater risk of increased signal noise compared to digital signals. This is primarily because analog signals are continuous and can be affected by various forms of interference and degradation as they travel through a medium. Factors such as electromagnetic interference, crosstalk, and attenuation can distort the signal, leading to a higher likelihood of noise, which reduces the overall quality and fidelity of the transmitted information.

Digital signals, by contrast, are discrete and can maintain their integrity over longer distances and in less-than-ideal conditions. They are also better equipped to incorporate error detection and correction methods, further minimizing the impact of any noise that might be present. Therefore, the increased susceptibility to noise in analog signals highlights the risk associated with their use compared to digital signals.
