Discrete-time systems are systems where signals are processed at distinct time intervals, often used in digital signal processing and control systems. They are characterized by sequences of data points, as opposed to continuous-time systems which operate over continuous time signals.

Discrete-time Systems

Discrete-time systems

Signals are functions that convey information about the behavior or attributes of some phenomenon, often represented as a function of time. They are fundamental in various fields such as communications, control systems, and signal processing, where they are analyzed and manipulated to extract or transmit information.

Digital Signal Processing (DSP) involves the manipulation of signals to improve or modify their characteristics, enabling efficient data transmission, storage, and analysis. It is fundamental in various applications like audio and speech processing, telecommunications, and control systems, leveraging algorithms to perform operations such as filtering, compression, and feature extraction.

Continuous-time systems are mathematical models that represent systems with inputs and outputs that vary continuously over time, typically described by differential equations. They are fundamental in fields like control theory and signal processing, where they are used to analyze and design systems that operate in real-time environments.
