damaged, (b) the original signal is not damaged but most of the noise

of the noise is gone. Include an explanation of why the different thresholds
have the effects that you observe.

- Homework 1: download PDF file. This homework
is due on Monday, September 23rd, in class. You will also need the
following matlab data file: data.mat. If you
are not familiar with matlab, you may want to have a look at the matlab
primer (download postscript file,
download PDF file)---I learned
most of what I needed to learn about matlab either by looking at this
primer, or by looking at the help, or by looking at other sample .m files
downloaded from the web.
IMPORTANT REMARK: The course packet is not yet available from the
Cornell Store... So I designed this homework so that the only reference
material that you will need to work on it is:
- Your notes taken in class.
- Matlab documentation.
- The chapters of Gersho&Gray already handed out.
- The chapters of Strang&Nguyen available from our
web page.
- Quiz on basic probability: download PDF file.
This quiz carries no weight, so feel free to do it or not. We encourage
you strongly to do it though, as it will be a good self-test for you
to decide whether you should be in this class or not. If you want us
to grade it, please be sure to turn it in by its deadline: 9/06.
Note: the answers are provided, you have to provide a derivation for
these answers.
