Digital Signal
A digital signal is a type of signal that represents data in discrete values, typically using binary code (0s and 1s). Unlike analog signals, which vary continuously, digital signals are more stable and less susceptible to noise, making them ideal for modern communication systems. They are commonly used in devices like computers, smartphones, and digital audio players.
Digital signals can be easily processed, stored, and transmitted over long distances without significant loss of quality. This is essential for technologies such as Wi-Fi, Bluetooth, and digital broadcasting, which rely on the efficient transfer of information in a digital format.
