I am trying to get a feel for Fourier transforms and would like some help.
Please show all work/explanations.
1. Let g(t) = x(2t) - x*(2t- 1/2T0), assume that X(jw) is known
Find G(jw) in terms of X(jw).
2. Let x(t) = 10sin(200t)/t
a) Find X(jw)
b) Let x(t) be the input to a continuous LTI system with impulse response h(t) = sin(100t)/t.
Find the output y(t)
c) Find the energy in x(t) and the energy in y(t).
Please see the attached file.
1. We can just use the properties of Fourier transform
Be careful with the last one, the time shifting is , and it ...
If provides examples of finding the Fourier transform of the signal. Then, it shows how to apply Fourier transform to find the output of the system given the impulse response. The solution is detailed and well presented.
