Appendix C: About the CD-ROM
CD-ROM Folders
Applets: The Learnware applets.
Chapter folders: Solutions to selected problems, MATLAB scripts, and all of the figures from the book, organized by chapter.
Sample exams: Sample midterm and final examinations.
The companion CD-ROM to the textbook contains files for:
•	Solutions to odd-numbered problems in each chapter plus sample exams in PDF format
The detailed solutions to the odd-numbered problems at the end of Chapter ,  are given in the file D:\Chapterk\Chapterkproblems.pdf, where D: is assumed to be the CD-ROM drive. The sample midterm tests and final exams are located in D:\Sample Exams\Covering Chapters 1 to 9, and D:\Sample Exams\Covering Chapters 10 to 17. All of the figures of each chapter can be found as TIFF files in D:\Chapterk\Figures.
•	Learnware applets (Discrete-time Convolution, Fourier Series, Bode plot)
The discrete-time convolution Java applet allows the user to enter the values of an input signal and an impulse response, and to choose to visualize the convolution either as a sum of scaled and time-shifted impulse responses, or as the sum of the values of a signal that is the product of the input signal and the time-reversed and shifted impulses response. The convolution applet can be run by pointing a Java-enabled browser to: 
D:\Applets\Convolution\SignalGraph\Convolution.html.
The Fourier series Java applet uses an intuitive graphical user interface. One period of a periodic signal can be drawn using a mouse or a touchpad, and the applet computes the Fourier series coefficients and displays a truncated sum as an approximation to the signal at hand. The convolution applet can be run by pointing a Java-enabled browser to 
D:\Applets\FourierSeries\FourierApplet.html.
The Bode applet is a Windows executable (.exe) file and can be found at D:\Applets\BodePlot\Bode.exe. Just double-click on it and you will be able to build a transfer function by dragging poles and zeros onto a pole-zero plot. Add a value for the DC gain of the overall transfer function and you will get the Bode plot showing the actual frequency response of the system together with its broken line approximation discussed in the text.
•	MATLAB M-files of selected examples in the text.  
These MATLAB script files, called M-files (with a .m extension) contain sequences of MATLAB commands that perform a desired computation for an example. The selected M-files are located in the Chapterk folders.
