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
to
You have to extract the digital spectrum of the
signal, find the two peaks at
and estimate
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
and teeta
NB:
1.Take
128 samples between [
,
]
2.Applying a Hamming Window help determining
the peaks more accurately.
wnd=ffshift (0.54+0.46* cos(2* pi*n (128))
3.Estimate
and teeta using
а weighted average as given below.
