1. Let the loop filter transfer function of a phase-locked loop be given as K1 G(s) = 1+ S (a) What is the lock range |Af| for this phase-locked loop? (b) What are the conditions on K and K for this phase locked-loop to be stable? (c) Let the input the phase-locked loop be given as (t) = (2f + )u(t) where u(t) is the unit step function. Calculate lim e(t) = lim ($(t) (t)). too too Does your result confirm your answer in part (a) above? 1.
