Educational Matlab GUIs
On this page are Graphical User Interfaces developed by the members of the Center for Signal and Image Processing (CSIP), a part of the School of Electrical and Computer Engineering at the Georgia Institute of Technology.
(updated 2-Jan-2008 for MATLAB version 7.2, some GUIs work on earlier versions of MATLAB)
Most of these GUIs also appear in the textbook Signal Processing First,
published by Prentice Hall Inc.

![]() | The Filter Design Demo is a program that designs simple FIR and IIR digital filters, along with tutorial visualizations of the filter design process. Features:
MATLAB Command Name: filterdesign Download: Requirements: Matlab 7.2 or greater Tested on: UNIX, Windows and Macintosh Last update: 2-Jan-08 |
![]() | PEZdemo allows the user to select the poles and zeros of a system and then change those poles and zero dynamically. The z-plane, Fourier domain and time-domain are all updated simultaneously. MATLAB Command Name: pezdemo Download: Requirements: Matlab 6.0 or greater Tested on: Windows Last update: 2-Jan-08 |
![]() | FourierSeriesDemo is a GUI that shows Fourier Series synthesis for different number of Fourier coefficients. Different signals can be selected: square wave, sawtooth, triangle and rectified sinusoids. MATLAB Command Name: fseriesdemo Download: Requirements: Matlab 5.2.1 or greater Tested on: Windows Last update: 03-Jun-09 |
![]() | PhasorRaces began as a speed drill for testing complex addition. Now it includes many other related operations that can be tested in a “drill” scenario: adding sinusoids, z-transforms, etc. A timer starts as soon as the problem is posed, so that a student can try to solve questions quickly and accurately. MATLAB Command Name: phrace Download: Requirements: Matlab 5.2.1 or greater Tested on: Windows Last update: 30-Mar-06 |
![]() | SinDrill is a program that tests the users ability to determine basic parameters of a sinusoid. After a plot of a sinusoid is displayed, the user must correctly guess its amplitude, frequency, and phase. MATLAB Command Name: sindrill Download: Requirements: Matlab 5.1 or greater Tested on: UNIX, Windows and Macintosh Last update: 30-Mar-06 |
![]() | ZDrill is a program that tests the users ability to calculate the result of simple operations on complex numbers. The program emphasizes the vectorial view of a complex number. The following six operations are supported:
MATLAB Command Name: zdrill Download: Requirements: Matlab 5.1 or greater Tested on: UNIX, Windows and Macintosh Last update: 30-Mar-06 |
![]() | CLTIDemo is a program that illustrates the relationship between the input and output of a continuous-time linear time-invariant (LTI) filter when the input is a sinusoidal signal. The user is allowed to control the parameters of both the input sinusoid and the analog LTI filter. MATLAB Command Name: cltidemo Download: Requirements: Matlab 5.1 or greater Tested on: UNIX, Windows and Macintosh Last update: 30-Mar-06 |
![]() | DLTIDemo is a program that illustrates the relationship between the input and output of a discrete-time linear time-invariant (LTI) filter when the input is a sinusoidal signal. The user is allowed to control the parameters of both the input sinusoid and the digital filter. MATLAB Command Name: dltidemo Download: Requirements: Matlab 5.1 or greater Tested on: UNIX, Windows and Macintosh Last update: 30-Mar-06 |
![]() | The Continuous-Discrete Sampling Demo is a program that shows the continuous and discrete spectra (and signals) during sampling. Features:
MATLAB Command Name: con2dis Download: Requirements: Matlab 5.3 or greater (not yet tested on Macintosh) Tested on: UNIX, Windows Last update: 30-Mar-06 |
![]() | The Discrete Convolution Demo is a program that helps visualize the process of discrete-time convolution. Features:
MATLAB Command Name: dconvdemo Download: Requirements: Matlab 5.2.1 or greater Tested on: UNIX, Windows and Macintosh Last update: 2-Jan-08 |
![]() | The Continuous Convolution Demo is a program that helps visualize the process of continuous-time convolution. Features:
MATLAB Command Name: cconvdemo Download: Requirements: Matlab 5.2.1 or greater Tested on: UNIX, Windows and Macintosh Last update: 2-Jan-08 |
