Discrete-time systems

Discrete-time systems are processes or devices that analyze or generate signals at specific, separate moments in time, rather than continuously. Imagine checking your pulse at regular intervals rather than constantly monitoring it. These systems take in data, like audio signals or sensor readings, at discrete points (samples), process this information, and produce an output that also occurs at these regular intervals. They are fundamental in digital technology, such as computers, digital audio, and communications, allowing complex information to be handled in manageable steps rather than continuous flows.
