+Some notes on the final exam.  Similar style to all the other tests I have given you.  Here is the {{formulasheet.pdf | formula sheet}} I'll be giving you.  Exam will cover material from L9 to L15 inclusive (not L16-17).  This overlaps with Assignment 2 Question 18 on.  Of course don't just forget the tools we developed in the first part of the course (e.g. sinc's, power densities, Nyquist sampling, integrating simple things, etc.), but the focus will be on the systems we discussed in the latter half.  Like the midterm the exam questions will go in order from L9 to L15.  I'll split the exam into relatively small questions so if you see lots of questions don't panic, its probably just lots of small parts.  As usual if you don't understand a question just move on to the next or to a section that you feel most confident on.  Remember, understanding the question is part of the test (that is why I don't elaborate on questions, if I don't say anything at least you are in the same boat as your classmates).

+Quiz 4 (this Thurs.) will just be concerned with Assignment 3 Questions 1-10 inclusive.  So there will not be any sequence detection, Viterbi stuff on this one.  I'll post the slides for the last couple of lectures tonight.

+One thing that I forgot is that the X (convolution) matrix should be normalized give the equations used in the notes.  The reason is that in the MMSE case we have the I/SNR term which effectively normalizes the noise power (variance) to a signal power of 1 (i.e. the identity matrix I).  When that's the case the X should be normalized.  Since X is made out of h you are best to just normalize h before using it to make X.  Normalize the components of h by the square root of the sum of the elements squared [or in Matlab, normalize by sqrt(sum(h.^2))].

+For tomorrow's quiz, I can't ask you all of Assig. 3 since we haven't finished all the material in it.  Only questions 1-6 (inclusive) are legit for Quiz 3.  As is what we have discussed over in L9 and L10 and L11 up to (and including) 11.4.  Here is the {{quiz3formula.pdf | formula sheet}} I'll be attaching to Quiz 3.

+Someone asked me about the quantizer for Lab 3.  Specifically the "formula" for it.  All I can really say is that it is pretty basic.  I implemented it in one line with MATLAB.  Remember all that a quantizer is is just an element that rounds off your input numbers.

+Assignment 3 questions are posted.  I have updated the quiz 3 and 4 dates in the wiki (both delayed by 1 week).
