Discrete Time Signals

Discrete time signals are sequences of data points that represent information at specific, separate moments in time, rather than continuously. Imagine recording the temperature once every hour instead of every second; each measurement is a discrete point in time. These signals are used in digital systems like computers, where continuous signals (like real-world sound or light) are sampled at regular intervals to be processed, stored, or transmitted. This approach allows for precise analysis, manipulation, and storage of information in a digital format, bridging the gap between real-world phenomena and digital technology.
