Paper Presentation on Digital Signal and Image Processing
Abstract:
A signal is defined as any physical quantity that varies with time, space or any other independent variable or variables. It may be a function of one or more independent variables. The signal itself carries some kind of information available for observation.
ANALOG SIGNALS: - The analog signals are continuous function of an independent variable such as time, space etc.
DIGITAL SIGNALS:- A discrete signal is a function of a discrete independent variable, which is an integer. A digital signal is same as discrete signal except that the magnitude of the signal is quantized.
