This text is intended for two-year and four-year electronics students, as well as industry practitioners who need to learn about applied Digital Signal Processing. This text is written in a very practical "hands-on" approach. It is written for those students who will apply and troubleshoot modern electronic systems. The approach used in the text presents critical ideas and then immediately applies them via software simulations and examples. These activities will clearly illustrate core concepts to increase understanding and aid retention. The CD-ROM included with the text contains five programs that support the hands-on activities. Three of the programs were specially prepared for beginners just learning DSP and two are demo versions of professional software used by DSP designers.
