المصدر: Educational Matlab GUIs في منتدى : قسم تبادل الخبرات الهندسية 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. / A Pearson Education Company / Upper Saddle River, New Jersey 07458 Filter Design Demo 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: Parks-McClellan FIR Design showing the iterations of the Remez Exchange method FIR Design with many different window types IIR Design of Butterworth filters Numerous plot options: magnitude/phase response, pole-zero diagram, and impulse response MATLAB Command Name: filterdesign Download: Filter Design Demo (Version 2.66) Requirements: Matlab 7.2 or greater Tested on: UNIX, Windows and Macintosh Last update: 2-Jan-08 PEZdemo 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: PEZdemo (Version 2.84) Requirements: Matlab 6.0 or greater Tested on: Windows Last update: 2-Jan-08 FourierSeries 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: FourierSeriesDemo (Version 1.20) Requirements: Matlab 5.2.1 or greater Tested on: Windows Last update: 30-Mar-06 PhasorRaces 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: PhasorRaces (Version 1.13) Requirements: Matlab 5.2.1 or greater Tested on: Windows Last update: 30-Mar-06 SinDrill 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: SinDrill (Version 2.09) Requirements: Matlab 5.1 or greater Tested on: UNIX, Windows and Macintosh Last update: 30-Mar-06 ZDrill 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: Add Subtract Multiply Divide Inverse Conjugate MATLAB Command Name: zdrill Download: ZDrill (Version 2.10) Requirements: Matlab 5.1 or greater Tested on: UNIX, Windows and Macintosh Last update: 30-Mar-06 CLTIDemo 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: CLTIDemo (Version 2.51) Requirements: Matlab 5.1 or greater Tested on: UNIX, Windows and Macintosh Last update: 30-Mar-06 DLTIDemo 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: DLTIDemo (Version 2.40) Requirements: Matlab 5.1 or greater Tested on: UNIX, Windows and Macintosh Last update: 30-Mar-06 Continuous-Discrete Sampling Demo The Continuous-Discrete Sampling Demo is a program that shows the continuous and discrete spectra (and signals) during sampling. Features: Users can change the input frequency and sampling rate. Frequency axis can be labeled in hertz or radians/sec. Reconstruction through D/A is also shown. MATLAB Command Name: con2dis Download: Continuous-Discrete Sampling Demo (Version 2.00) Requirements: Matlab 5.3 or greater (not yet tested on Macintosh) Tested on: UNIX, Windows Last update: 30-Mar-06 Discrete Convolution Demo The Discrete Convolution Demo is a program that helps visualize the process of discrete-time convolution. Features: Users can choose from a variety of different signals. Signals can be dragged around with the mouse with results displayed in real-time. Tutorial mode lets students hide convolution result until requested. Various plot options enable the tool to be effectively used as a lecture aid in a classroom environment. MATLAB Command Name: dconvdemo Download: Discrete Convolution Demo (Version 3.07) Requirements: Matlab 5.2.1 or greater Tested on: UNIX, Windows and Macintosh Last update: 2-Jan-08 Continuous Convolution Demo The Continuous Convolution Demo is a program that helps visualize the process of continuous-time convolution. Features: Users can choose from a variety of different signals. Signals can be dragged around with the mouse with results displayed in real-time. Tutorial mode lets students hide convolution result until requested. Various plot options enable the tool to be effectively used as a lecture aid in a classroom environment. MATLAB Command Name: cconvdemo Download: Continuous Convolution Demo (Version 2.12) Requirements: Matlab 5.2.1 or greater Tested on: UNIX, Windows and Macintosh Last update: 2-Jan-08 Download Link
