Which type of signal is less prone to interference and noise?

Digital signals are less prone to interference and noise primarily because they represent information in discrete values (0s and 1s) rather than as continuous waves, as is the case with analog signals. This binary representation allows digital signals to be more robust against degradation. When interference occurs, it may alter the signal somewhat; however, as long as the original digital bits can be distinguished from noise, the integrity of the data can often be preserved. Digitally encoded information can utilize error detection and correction techniques, which can identify and rectify errors caused by noise and interference. This ability to recover the intended signal amid noise and interference is a significant advantage, especially in environments where these issues are prevalent. In contrast, analog signals can be significantly affected by noise, as any interference alter the continuous waveforms directly, leading to distortion, which can be difficult to correct. Therefore, the resistance of digital signals to degradation and their ability to maintain clarity make them the preferred choice in many communication applications where noise and interference are concerns.
