Create the transfer function (output/lnput) r(t)/y(t) of a system whose input and output are related by the following differential equation: y^(iv) + 2y''' + 6y'' + 8y' + 4.8y = r'' + 9r' + 6r. ii) Use Laplace transform to obtain R(s)/Y(s) Transfer function. iii) Use MatLab to represent this transfer function as row vectors. iv) Use Matlab to plot the polynomial solution for time domain r(t)/y(t). v) Use Matlab to obtain the Laplace transform of r(t)/y(t) and compare it to your results on (ii), Did you obtain the same results? explain
