As we all know the Rectangular pulse is defined as , exists for a duration of T sec symmetrical with respect to y-axis as shown
Fourier Transform is
The Energy Spectral Density of the given signal will be
Pb2. Let and find the Energy Spectral Density of .
Ans:- The Energy Spectral Density of is
, then Fourier Tansform of is
Pb3. The Energy contained with in the band , then find the ESD , for any Energy of a signal can be defined
Pb:-find the Auto correlation function of .
Ans:- Auto Correlation Function Energy spectral Density
we know that Fourier Transform of
By using the above rule
Now the Energy Spectral Density
by finding the inverse Fourier Transform of
Auto Correlation Function =
