Loop release
Phase-locked loop

Let's assume the loop is hooked and subjected to an input phase ϕ _e . If the variations in the phase ϕ _e are too great, the loop no longer follows and stalls: we then lose synchronism between the signals y _e and y _s .

Often, we're interested in pulsation stall: with the loop hooked, we slowly vary the pulsation of the input signal and watch when we lose synchronism.

The pulsation stall (or synchronization) range is the maximum pulsation deviation Δω _max (on either side of pulsation ω _...
