1 Advanced Digital Signal Processing Abdellatif Zaidi † Department of Electrical Engineering University of Notre Dame azaidi@nd.edu Outline: 1. Introduction 2. Digital processing of continuous-time signals • Retition: Sampling and sampling theorem • Quantization • AD- and DA-conversion 3. DFT and FFT • Leakage effect • Windowing • FFT structure 4. Digital filters • FIR-filters: Structures, linear phase filters, least-squares frequency domain design, Chebyshev approximation • IIR-filters: Structures, classical analog lowpass filter approximations, conversion to digital transfer functions • Finite word-length effects 5. Multirate digital signal processing • Decimation and interpolation • Filters in sampling rate alteration systems • Polyphase decomposition and efficient structures • Digital filter banks Parts of this textbook have been realized in close collaboration with Dr. Joerg Kliewer whom I warmly thank. 6. Spectral estimation • Periodogram, Bartlett’s method, Welch’s method, Blackman-Tukey method • ARMA modeling, Yule-Walker equation and solution Literature • J. G. Proakis, D. G.
