What is an advantage of using digital systems over analog systems?

Digital systems provide several key advantages over analog systems, primarily in terms of accuracy and noise immunity.

When it comes to accuracy, digital signals represent data in discrete values (such as binary 0s and 1s), which allows for precise representation and manipulation of information. This discrete nature helps avoid the continuous variations that can lead to errors in analog systems, where small fluctuations can significantly affect performance.

Noise immunity is another significant factor. Digital systems are less susceptible to noise because a digital signal can maintain its integrity despite interference. Since digital signals have defined high (1) and low (0) states, they can often be distinguished clearly even in the presence of some level of noise. Analog systems, on the other hand, can be dramatically affected by noise, which can distort the signal and lead to inaccurate data processing or communication.

These characteristics make digital systems particularly beneficial in a variety of applications, especially where precision and reliability are crucial, such as in computing, telecommunications, and audio/video processing.
