don't use the Laplace method in the solution

a)For the signal x(t) 9+a i)Find X (jw) ii) Find the total energy of x(t) (3) b)if y(t)=y(t) = 24V2 cos(10t) i)Find and draw y(jw) ii) Find the total energy of y(t) (4) c)For an LTI system the relation between the input and output is given as dy(t) +6 dy(t) dt dt + 5y(t) = X(t) + 2x(t) Using Fourier transform find the step response of the system
