E-Book on DSP Theory with Interactive iOS, Java, and Android Simulations

Internet and multimedia technologies have had a profound impact in STEM education in the past decade. The increase in the use of mobile devices among students adds another novel dimension to course design and delivery. Furthermore, the traditional textbooks are being replaced and supplemented by inexpensive and mobile e-books, and hence there is an opportunity to integrate the multimedia and mobile technologies in an e-learning environment. As a part of the NSF TUES phase 3 project for development and dissemination of the J-DSP software (Award no. 0817596), we are developing an e-book, with associated software and multimedia tools, for teaching signal processing to undergraduate students. The e-book covers DSP theory, problems and examples demonstrated using J-DSP, a freely available online DSP simulation environment. Each simulation in the e-book is hyperlinked to an interactive web page that uses Java software, videos and MATLAB scripts to deliver the technical content. Video demonstrations of simulations in performed in a computer as well as iOS and Android mobile devices are also provided. The proposed e-learning environment will be employed in Signals and Systems, and Digital Signal Processing courses at Arizona State University during the spring 2013. The proposed learning methodology will be assessed continuously throughout the semester with specially tailored assessment instruments. We believe that such an integrated, anytime-anywhere e-learning framework with rich multimedia content will be a convenient mobile platform that will lead to effective student learning.
