8.  Find the Fourier transform of the half cosine pulse as shown below : 

Your Answer: Option (Not Answered) Correct Answer: Option B Explanation: The given signal can be expressed as multiplication of x_{1}(t) and x_{2}(t) as shown below. where A = 2, T/2 = 0.25 => T = 0.5 ∴ x(t) = x_{1}(t) x x_{2}(t) => X(f) = X_{1}(f) * X_{2}(f) Now X_{1}(f) = [δ(f  f_{0}) + δ(f + f_{0})] = [sin c [T(f  f_{0})] + sin c[T(f + f_{0})]]
Now, A = 2, T = 0.5 and f_{0} = = 1 => X(f) = 0.5[sin c (0.5(f  1)) + sin c (0.5(f + 1))]. Learn more problems on : Exam Questions Papers Discuss about this problem : Discuss in Forum
