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.
Page 1. Cover page
- 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.
Page 6 -
- 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)?
