- Continuous-Time and Discrete-Time Signals and Systems
A system is usually understood to be an engineering device in the field, and a mathematical representation of this system is usually called a system model. It can be defined as the mathematical relationship between an input signal and an output signal. The word system refers to many different things in engineering, It may be refers to: Tangible objects: such as software systems, electronic systems, computer systems, or mechanical systems. Theoretical objects: such as a system of linear equations or a mathematical inputoutput model. 2. Signals
