A two loop position control system is shown below.

The gain \(\mathrm{K}\) of tachogenerator influences mainly the
(a) peak overshoot.
(b) natural frequency of oscillation.
(c) phase shift of closed loop transfer function at very low frequencies \((\omega ightarrow 0)\).
(d) phase shift of closed loop transfer function at very high frequencies \((\omega ightarrow \infty)\).
