Question: A first-order PLL is operating with zero frequency and phase error when a step in frequency of magnitude is applied. The loop gain K

A first-order PLL is operating with zero frequency and phase error when a step in frequency of magnitude Δω is applied. The loop gain Kt is 2π(100). Determine the steady-state phase error, in degrees, for Δω = 2π(30), 2π(50), 2π(80), and 2π(80), rad/s. what happen if Δω = 2π(120) rad/s?
