Dec 15, 12:30pm -- It turns out that the library inadvertently pulled the text solutions and returned them to me. Obviously they were meant to stay in the library. I JUST returned them, and they should be available to you again for the rest of today and tomorrow, same call # as before (UWD 1461).
Dec 12 - The exam equation sheet is ready and can be found here.
Nov 30 - I have prepared an extensive, time-consuming handout. It will require a fair bit of study, but it gathers a huge amount of information on one page.
Nov 14 - Azadeh apparently told you in tutorial last week that she would be preparing some notes to clarify some point. Those notes are now available: page 1 and page 2.
Nov 7 - Nezam prepared a handout with more examples for discrete-time pole-zero sketching.
Oct 12th -- Two weeks ago the tutorial took place on Thursday only. I had promised to scan the notes for you. Sorry that it has taken this long. The notes can be found here. Page 10 was placed first; pages 1-9 follow in proper order thereafter.
A few things: No calculators or any other aids, no "cheat sheet" You will be provided with a page of equations. You can see my exam for last year's class here. You had asked about last year's midterm, it is here. The exam will be roughly similar to last year's, except one sixth shorter, and will have 4-5 questions If the difference in your performance between the midterm and final is significant, then I will adjust the weighting of the midterm (currently 20%) and final (currently 60%) by plus/minus 5% in your favour. Important Dates: Final Class Thurs Dec 1 Review Lecture Tues Dec 6 1:00-2:30 CPH 3374 Final Exam Fri Dec 16 12:30-3:00 RCH 103/105 Office Hours: Regular hour Fri Dec 9 12:30-1:30 Cancelled; you have an exam Nezam Tues Dec 13 10:00-11:30 E2 1303C P. Fieguth Tues Dec 13 1:00- 2:30 DC 2615 Azadeh Thurs Dec 15 10:00-11:30 E2 1303C Nezam Thurs Dec 15 1:00- 2:30 E2 1303C
- Question 1: (a) - (c) --- Azadeh - Question 1: (d) --- Prof. Fieguth - Question 2: --- Nezam - Question 3: (a) - (c) --- Azadeh - Question 3: (d) --- Prof. FieguthThe average was highest on Q1a-c, lowest on Q1d. The variability was highest on Question 3.
A solutions manual for your textbook has been placed in the library as call number UWD 1461. We are also considering placing some solutions, previously-developed by TAs, on-line. Also see university page on plagiarism and OPD.
The tentative schedule is as follows:
Tuesday 3:30 - 4:30 Azadeh Mohebi TA office E2-1303C (personal office DC-2640) amohebi@engmail Wednesdays 3:30 - 4:30 Nezam Nezam.-Kachouie TA office E2-1303C (personal office DC-2626) nnezamod@engmail Fridays 12:30 - 3:30 Paul Fieguth DC-2615To talk with me, the easiest arrangement is to ask questions before or after class. I will generally try to arrive ahead of time. There will, of course, be additional office hours scheduled before the midterm and final exams.
The Lathi text is comprehensive, but a bit wordy. As much as possible I will try to save you time by suggesting sections to skim and acquire familiarity, and limit the number of sections to read in detail. Although some of the readings appear long, in terms of number of pages, the Lathi book has MANY examples and illustrations, so the amount of actual reading is not so bad. Also note that the book gives Matlab examples at the end of every chapter.
Signals and Systems material builds very steadily over the term. Do NOT fall behind in the reading! The following schedule is somewhat tentative:
Material Sections to Skim Sections to Read Suggested Problems Background B.5 B.1-B.3, B.5-1 B.2,3,35 Introduction 3.4 1.1-1.3, 3.1-3.2 1.3-1 Basic Signals 1.5 1.4, 3.3 1.4-1,2,4,6, 3.3-3,4 System Properties 1.6-1.8 1.7-1,2,7,8,9,11,12 Impulse Response 2.1-2.2, 3.5-3.6 2.3, 3.7 Convolution 2.4, 3.8 2.4-4,7,16,18, 3.8-11 LTI Eigenfunctions 2.4-4, 3.8-3 Laplace Transform (Omit 4.1-1) 4.1, 4.2, 4.11 4.11-1,2,3 Z Transform (Omit 5.1-1) 5.1, 5.2, 5.9 5.9-1,2,3,4 Tranforms and DEs 4.3, 5.3 Focus on 4.11, 5.9 4.3-5,6, 5.9-7, 5.3-23 (for both causal and anticausal) Transform Spectra 5.5 4.8, 4.9, 5.6 4.8-4a,, 4.9-1,2, 5.5-3,10ab, 5.6-1,4 Fourier Series 6.1, 6.2 6.3 6.3-1,3,4 Fourier Transform 7.4, 7.5 7.1-7.3 7.1-1,3a,4,5, 7.3-10,11 Signal Modulation 7.7.1-2 p.712, 7.8 7.7-1ab, 4ac Sampling 8.3, (8.4-8.5) 8.1, 8.2 8.1-1,5,6,8, 8.2-7,14 DT Fourier 9.4, 9.6 9.1-9.3, 9.5 9.1-4,5,6, 9.2-3,6

% % The function is called from Matlab as y = lab1(sys,x) % % sys is an integer, {1, 2, or 3}, corresponding to systems S1, S2 and S3 % x is a vector of length 201, corresponding to a time n= -100,...,100 % y is the system output, a vector of length 201 % % Examples: % x = zeros(201,1); x(101) = 1; % x is the unit impulse function % y = lab1( 1, x ); % response of system 1 % % x = zeros(201,1); x(101:201) = 1; % x is the unit step function % y = lab1( 3, x ); % response of system 3 %
% % LAB3_FT % Compute the Fourier transform of a signal x. % t is a vector of times, regularly spaced, % corresponding to the elements of x. % % dw is an optional parameter, suggesting fineness % of sampling in the frequency domain % % The function returns the transform X, where the elements of X % correspond to the frequencies given in vector w. % % [w,X] = lab3_ft( t, x, dw ) % % Then to plot the real part of X, for example, use plot(w,real(X)) %
