A open loop transfer function of a unity negative feedback control system is given by, G(S) = . An integral controller having transfer function G_C(s) = is connected in the forward path of the system, to obtain a peak overshoot of 25% the value of the system gain ‘k’ is

A 100 MHz electrical field travelling in dielectric of region 1 is normally incident on a boundary with dielectric region 2. The representation for the incident electric field (in the first dielectric) is  exp (-j10z). The velocity in the second dielectric is  m/sec. Both dielectric are characterized by .

The intrinsic impedance of electrical of region 1 is
