10/8/07: Discussion notes for MK's discussion today are here
10/5/07: Find the video of the "last lecture" of Randy Pausch from a link on his webpage here. Its not related to the course contents though, at least not directly.
10/5/07: The solutions to quiz are now posted.
10/4/07: HW 6 and solutions to HW 5 are posted!
9/21/07:Correction in HW 3 solutions : The overshoot in Prob 9 is 0.18, instead of 1.18. Thanks to David for pointing that out. The correct solutions are now posted.
9/21/07: For those who came to Pulkit's discussion on Wednesday. We decided there was a mistake for which we discussed for a while. Well, there was no mistake! Continuous time Fourier Series coefficients for x(t) and x(t/M) are the same (for M>0). The reconstruction is different because w_o is different for the two. If you still have questions, Pulkit can put up a pdf for the derivation. Email him!
9/20/07: Homework 4 is up. Good luck! Remember, the Quiz is next Tuesday. Also, Homework 3 solutions have been posted.
9/18/07: Change in Office Hours of Mary. Her office hours would now be from 12:45 to 1:45 on Thursdays.
9/17/07: Change in HW3, Problem 1.b. The plot of |G(e^(jw)| should be 3/4*|G(e^(jw)|.
9/14/07: Homework 3 is posted. So also are the solutions to Homework 2.
9/13/07: Oh, poor Ol' Fourier! Read his biography here.
9/10/07: Please send your scores to ee120.gsi@gmail.com, and NOT to the GSI's! Thanks.
9/9/07: 'basis.mat' is now up (yay!). Check the 'Homeworks' page. Oh, and the optional problem would not be graded. Its only for personal enrichment.
9/6/07: Homework 2 posted! Check the Homeworks link. Its due on next Thursday.
9/5/07: Office hours for this week (and ONLY this week):
Mark Johnson: 3-4 PM, Thursday, Cory 197
Mary Knox : 12:30-1:30 PM, Thursday, Cory 197
Pulkit Grover: 1-2 PM, Friday, Cory 197

9/4/07: In class we showed that if the sum of h(k) for all k was equal to infinity, then it was NOT BIBO st able. Thus, the contrapositive is true.
In order to solve for C_1 for the difference equation, we could NOT use the equation y[n]=C_1(-1/2)^n-(1/2)*(1/2)^ n for the case when n=-1 because the equation holds only for n>=0. Thus, first solve for y[0] (from LCCDE).
y[0]=x[0] - x[1] -(1/2)*y[-1]=1/2;
Now plug into the solution for y[n]=y^h[n]+y^p[n] to get :
C_1(-1/2)^0 - (1/2)*(1/2)^0=1/2;
Thus C_1 = 1
