Basics of Signals and Systems
Computer Assignment I
Due: 26 October 2011, Wednesday by 17:00 in the homework box
Write your own MATLAB code to plot sinusoidal signals as a function of time. The program
should be able to plot both sine and cosine signals of the form
A
sin(
w
o
t
+
φ
) and
A
cos(
w
o
t
+
φ
).
Use the last two digits of your ID number as the
A
value; use the three digits before the last two
digits as the
f
o
value. Use the uniformly distributed random number generator in MATLAB
to generate the phase
φ
of the signal randomly in the interval
φ
: [

π, π
]. Select a suitable
uniform sampling interval
T
s
from the set [

1] to increment the
time (time units in seconds).
a) Plot your results for two cosine and two sine functions whose parameters are generated
as described above. Specify the parameter values
A, f

, φ, T
s
that you have used in each case.
The program should also calculate the time shift Δ
