Fundamentals of discrete-time signal Discrete-time signals: processing • Signals: physical quantities that change as a function of time, space, or some other dependent variable. Objective of this chapter: • Analysis of signals require mathematical signal To focus attention on some important issues of models that allow one to choose the ...
Signals Signals A signal is a function representing a physical quantity, and typically it contains information about the behaviour or nature of the phenomenon. From a communication point of view a signal is any function that carries some information. An example of a speech signal Classification of Signals and System: ...
Signal : Any physical quantity that varies with time, space, or any other independent variable or variables. Classification of Signals : Continuous -Time Signals Discrete -Time Signals Continuous -Valued Signals Discrete- Valued Signals Continuous -Time Signals : defined for every value of time take on values in continuous interval (a ...
