Course Description
This course provides a basic introduction to the theory of digital signal processing. The course will concentrate on signal analysis using Fourier transforms, linear system analysis and filter design. In the lab, MATLAB will be used extensively for Fourier analysis and designing of digital filters.
Expected Outcomes
Upon completion of this course, students will: Be able to analyze signals and systems using the discrete-time and discrete
Fourier transforms. Become familiar with the different basic digital filter types: low and high pass,
band-pass and band-stop, differentiator, integrator, Hilbert transformer, IIR, FIR, linear phase and minimum phase.
Be able to design FIR linear phase and IIR filters to meet a given specification using MATLAB.
Understand the potential effects of coefficient quantization and system implementation on the performance of digital filters.
