Digital signal processing with MatLab and DSP kits

A methodology, based on progressive steps, has been developed, so that the students be prepared to design and implement typical industrial projects, such as digital filters, voice processing algorithms, and others, and also be able to correlate this knowledge with other disciplines. They start with an analog system, described by a differential equation, from which a generic discrete equation is generated. The projects are initially simulated with MatLab, and they are then implemented with DSP TMS320C31. The projects are always based on a fundamental equation of differences, representing a digital filter: this is very important for the study of digital processing concepts, such as system stability, system order, computational complexity, and so on. The simulation helps the students to understand a system digitalization process. The results obtained with the students in the course show the efficiency of this methodology.
