Digital Signal (DS)

A Digital Signal (DS) is a type of signal that uses discrete, separate values—usually binary numbers (0s and 1s)—to represent information. Unlike analog signals, which vary smoothly over time, digital signals change in steps, making them more resistant to noise and distortion. This digital format allows for accurate data transmission, processing, and storage, forming the backbone of modern communication systems like internet, mobile networks, and digital audio. Essentially, digital signals convert real-world information into a series of simple, manageable bits that technology can easily interpret and manipulate.
