The
Fourier
Series is a mathematical tool which is commonly used for solving many different engineering
problems. In
Dynamic Systems work, the Fourier Series is useful for
understanding frequency characteristics of first and second
order systems.
The
MATLAB GUIs are available for both MATLAB 6.5 and 7.0. See the general MATLAB GUI instruction file below for more
information on system requirements and how to run the
GUIs. The MATLAB GUI .zip file contains a document of
suggested exercises to be performed with the GUI.

Asks the students to develop
their own LabVIEW GUI to study the Fourier series and time
and frequency signals. LabVIEW notes are available
here. |

Allows
users to change the properties of up to 5 sine waves, sum them,
and view the result in the time and frequency domain.
Pre-programmed sample signals and their Fourier series
representations can also be viewed.

Allows
the user to change the parameters (amplitude and frequency) of
5 different sine waves and view the result of their summation
in both the time and frequency domain. The user can also
use those waves to approximate either a square, sawtooth, or
traingle wave. A low-pass and band-pass filter can also
be applied to the summed signals.
