[944] Optional homework

[Gautam Iyer]

Hi All,

I put up an optional homework. It is never due. The problems are good
practice on many of the concepts you've learned so far.

Since previous years exams did not have any problems on the discrete
time models, I included a few problems on this.

I put up answers to some of those problems. No solutions or answers will
be given to the others, as some of them will be on your next homework.

Best,

Gautam

PS: As usual, solutions to HW3 will post sometime tomorrow (after the late
    deadline passes)
