Modelling and simulation of equations for signals and systems

Abstract

Nowadays, everyone wants to solve the problem easily without burden themselves. Base on that factor, the simulation to convert the time signal to the representations for signal is done. The representations for signal that have been focused are Fourier transform, Laplace transform and Z transform. Graphical User Interface (GUI) in Matrix Laboratory (MATLAB) software is used to create the interface of these three representations for signal. The user just need to enter a desired time signal equation into edit text box and by a single click on the specified button, the representation for the signal will be displayed in the text box and the graph will also appear. If before, users must refer to the table every time they want to convert the time signal to representations for signal but now is not to do so. Overall, this project was done successfully and the result that has been obtained was similar to the standard value.
