Summary

Students learn digital signal processing theory, including discrete time, Fourier analysis, filter design, adaptive filtering, sampling, interpolation and quantization; they are introduced to image processing and data communication system design.

Content

  1. Basic discrete-time signals and systems: signal classes and operations on discrete-time signals, signals as vectors in Hilbert space
  2. Fourier Analysis: properties of Fourier transforms, DFT, DTFT; FFT.
  3. Discrete-Time Systems: LTI filters, convolution and modulation; difference equations; FIR vs IIR, stability issues.
  4. Z-transform: properties and regions of convergence, applications to linear systems.
  5. Filter Design: FIR design methods, IIR design methods, filter structures.
  6. Stochastic and Adaptive Signal Processing: random processes, spectral representation, Optimal Least Squares adaptive filters.
  7. Interpolation and Sampling: the continuous-time paradigm, interpolationthe sampling theorem, aliasing.
  8. Quantization: A/D and D/A converters.
  9. Multi-rate signal processing: upsampling and downsampling, oversampling.
  10. Multi-dimensional signals and processing: introduction to Image Processing.
  11. Practical applications: digital communication system design, ADSL.
