EE2S31 Signal Processing
Introduction
Signal processing plays an important role in many applications, such as consumer electronics (mp3 player, mobile phone, CD player, TV (HD)), radar and medical applications. This course covers two topics: an introduction into random signals (following the course Probability and Statistics, EE1M31), and a first course on digital signal processing (following the course Signals and Systems, EE2S11).
For study guide information (teaching goals, etc.), see Study guide.
In this course the following topics are discussed:Digital signal processing
The part on signal processing considers in particular onedimensional signals and discusses digital filter design, filter structures, the DFT spectral analysis, filter implementation, and multirate filters. Repetition: (discretetime) signal processing, poles and zeros, filter functions
 Nonideal sampling and reconstruction
 Sampling in the frequency domain, the Discrete Fourier Transform
 Spectral analysis and filtering using the DFT
 Efficient computation of the DFT: the FFT
 Digital filter structures based on allpass filters
 Quantization and rounding errors in filters
 Analogtodigital conversion using sigmadelta modulation
 Multirate signal processing
Stochastic processes
The part on stochastic processes introduces the concept of stochastic models and random processes to describe systems and signals that are not deterministic in nature. Pairs of random variables
 Random vectors & conditional probability models
 Sums of random variables,
 Derived random variables
 moment generating function
 central limit theorem.
 Deviation of RVs from its expected value:Markov ineq., Chebyshev ineq. and the Chernoff bound.
 Sample mean, unbiased estimators, consistency.
 Estimation of Random variables, blind estimation, conditional estimation, MMSE, MAP and ML estimators.
 Stochastic processes.
 Estimation of autocorrelation functions, ergodicity, the autocorrelation function & signal processing for WSS signals.
 The autocorrelation function & signal processing, PSD, CPSD & frequency domain relationships.
Exam
The examination of the course is conducted in two parts (in the middle and at the end of the quarter). Both partial exams contain a 50/50 distribution of questions on signal processing and stochastic processes.The final grade is the average of the two partial exam results. This calculation is done with one decimal place, and the final grade will be rounded to half a digit. The reexamination is conducted in one part (over all lecture material). The result of the partial exams expires for reexamination and is not transferable to the next year.
Be sure to register for each partial exam on Osiris!
The exams are closed book. You are permitted to bring one A4size page (2 sides) of HANDWRITTEN notes.
