Abstract :
Using a novel cycle-slip criterion, two methods of computing the lock-in frequency of phase-locked loops are reported. The lock-in frequency of a second-order loop with sinusoidal phase detector is presented as a function of system parameters, and useful estimates by the pull-out and pull-in frequencies are given.
