Matlab problem (HW#9)
The objective of this problem is to use
fft
and
fftshift
Matlab commands to numerically
calculate and represent the FT of the
oboe
,
sax
,
piano
and
cosine
signals from Discussion
Session #7 (
http://www.ece.umn.edu/class/ee3015/3015_Discussion_7.pdf
).
You are required to turn in the following:
•
Matlab plot of the FFT of the
oboe
,
sax
,
piano
and
cosine
signals (just the
magnitude). Make sure you scale your horizontal axis correctly (it should
represent frequency either in Herz or in radians). Include comments on the results
obtained.
•
Matlab plot of the Fourier Series coefficients of the
oboe
,
sax
,
piano
and
cosine
(just the magnitude) obtained by doing “peakpicking” on the FFT (see hints
given below). Compare the coefficients with the ones obtained in Discussion #7.
•
Matlab code.
The submitted work should be your own. You can (and indeed you are encouraged to)
discuss this assignment with other students, but the Matlab code you turn in should
