What is one key benefit of using digital signals over analog signals?

One significant benefit of using digital signals is their reduced susceptibility to noise and interference. In contrast to analog signals, which can degrade over distance and are easily affected by electrical noise, digital signals maintain the integrity of the transmitted data better. This robustness is primarily due to how digital signals represent information as discrete values (usually as binary code), allowing for clearer distinction between high and low states. Even if a digital signal experiences some distortion due to noise, it can often be reconstructed accurately by the receiving equipment, preserving the quality of the communication.

This resilience makes digital signals particularly advantageous for modern communication systems, where clarity and reliability are essential, especially in environments with potential electromagnetic interference. The capacity to maintain signal quality leads to improved performance in applications such as broadcasting, telecommunications, and data transmission, highlighting why this option is recognized as a primary benefit of digital over analog signals.
