Digital Signal Processing

At the end of this course, the students should be able to: 1. illustrate the basic concepts of DSP theory such as sampling theory and discrete frequency; 2. differentiate DTFT, DFT, and FFT; 3. define the concept of filtering, time-frequency methods and identify the relations between them; 4. differentiate FIR and IIR filters, stating their frequency response and characteristics; 5. design and implement FIR and IIR filters using different methods; and 6. demonstrate successfully the design and implementation of DSP filter using MATLAB.

Digital Fourier transform; Fast Fourier transform; approximation problem in network theory; synthesis of low-pass filter; special transforms and their application in synthesis of high-pass and band-pass filters; digital filtering transfer function analysis; one-dimensional recursive and non-recursive filters; computer techniques in filter analysis; realization of filters in hardware and software; basic image processing concepts.
