Question

Write
a program that will take a
128 element
vector known to contain cos (wot +6) for arbitrary
teeta and 0.5 <wol 1.5. The values of 't' go from
$- \pi$
to
$\pi$


You have to extract the digital spectrum of the
signal, find the two peaks at
$+ or - w0$
and estimate
$w0$
and teeta


Suppose the data given above has added
"White Gaussian noise". This can be generated
by randn() in python. The extent of the noise
in amplitude (i.e., 0.1* randon (N), where
'N' is the number of samples). Repeat the
problem and find
$w0$
and teeta
NB:
1.Take
128 samples between [
$- \pi$
,
$\pi$
]

2.Applying a Hamming Window help determining
the peaks more accurately.
wnd=ffshift (0.54+0.46* cos(2* pi*n (128))
3.Estimate
$w0$
and teeta using
а weighted average as given below.​
