ECE 4250

Digital Signal and Image Processing

Course Description

Course information provided by the Courses of Study 2020-2021.

Introduces statistical signal processing. Signal representation and manipulation are covered via correlation and using the DFT/FFT to estimate other transforms; applications of these topics are then covered, including quantization, quantization effects in digital filters, multirate DSP, filter banks, delta-sigma modulation, power spectrum estimation, and introductions to Wiener and Kalman filtering and image processing.

When Offered Spring.

Prerequisites/Corequisites Prerequisite: ECE 2200/ENGRD 2220. Culminating design experience (CDE) course.

• Be able to draw Fourier spectra in both discrete-time frequency and continuous-time frequency, while undergoing common operations such as filtering, upsampling, downsampling, A/D and D/A.
• Given a finite-duration, discrete-time signal, be able to estimate the discrete-time Fourier Transform and the original frequency content in the signal (e.g., the continuous-time Fourier Transform) and give bounds on the accuracy of the estimate.
• Given a continuous-time signal with certain frequency- and time-based characteristics, be able to design a (real-world, non-ideal) system to appropriately sample the signal such that desired characteristics are maintained to within given tolerances.
• Given a digital audio (1-d) or image (2-d) signal, be able to select an appropriate frequency- based transform suitable for the desired or specified processing.
• Quickly prototype and debug signal processing algorithms using Matlab.
