EE 523 - Applications of Digital Signal Processing3 lecture hours 0 lab hours 3 credits Course Description This course builds upon the EE-3220 DSP lecture course. It is heavily laboratory- and applications-oriented, enabling students to implement powerful algorithms on actual DSP hardware utilizing the C programming language. Such algorithms as FIR and IIR digital filters, adaptive and multirate filters (interpolator), modulators and demodulators, correlators and discrete and fast Fourier transforms are programmed. The hardware is capable of processing audio signals in realtime, effectively demonstrating the power of the techniques. An individual project is required. (prereq: EE-4021 or equivalent, consent of instructor) Course Learning Outcomes Upon successful completion of this course, the student will be able to: • Determine the appropriate system design for DSP applications. • Be proficient in the C programming language of a DSP chip. • Understand the implementation tradeoffs of DSP algorithms including FIR and IIR digital filters, adaptive filters, least mean square (LMS) algorithm, multirate filters, interpolation and decimation, discrete and fast Fourier transforms, modulators and demodulators, phase locked loop. • Utilize an evaluation module for a DSP chip. • Write and test in the laboratory programs in the C progamming language of a DSP chip to implement the algorithms described above.
