Laboratory Project 1
Waveform Synthesis and Spectral
Analysis
Suggestions for a Good Laboratory Report
-
The following suggestions, specific to
the various
sections of your lab report are meant to be a listing of minimum
expectations.
-
There is a lot to discover about ECOMMS
as you do
the labs - so keep your eyes and ears open - and record everything!
(Also
have fun...).
-
Feel free to experiment - i.e. do more
than the suggested
lab activity. This will improve your lab score.
-
You are encouraged to observe and
record more than
the minimum suggested here - this will also improve your lab score.
-
Talk to the instructor often -
especially when you
see/hear something that you cannot explain.

Project Number
-
Project Title.
-
Course Number.
-
Names of Group Members.
-
Date handed in.
Pages 2 - 5
-
Objective
-
Equipment and Software used.
-
List exactly what you used.
-
Approach (Theory)
-
Provide a description (with releveant
mathematics)
of how random variable theory allows us to synthesize signals of
arbitrary
SNR.
-
Provide a description (with relevant
mathematics)
of how the DFT can be used to approximate the CFT. Under what
conditions
is the approximation valid?
-
Part 1 and 3: What do we
expect to see in
the time and frequency domains when we vary the SNR?
-
Part 4: What do we expect to
see in the time
and frequency domains?
-
Procedure
-
List what you actually did.

-
Results (tables and graphs)
-
Matlab figures of the time and
spectral domain representations
of the various waveforms - label all axes.
-
Discussion of Results and Conclusions.
-
Did you hear and see what you
expected in the time
and spectral domains? If not, why not?
-
Why is it important (and useful) to
observe signals
in the spectral domain? How does the FFT allow us to do this?
-
What can the tecnhiques learned in
this lab be used
for (as related to ECOMMS)?
