After being relieved by General George S. Patton's U.S. Third Army, the 101st retook the town. On January 2, 1945, the 1st Canadian
Phase-locked loop ranges between initial and final phase deviation is larger than formula_13, we say that cycle slipping takes place. Here, sometimes, the limit of the difference or the maximum of the difference is considered Definition of lock-in range. If the loop is in a locked state, then after an abrupt change of formula_15 free within a lock-in range formula_16, the PLL acquires lock without cycle slipping. Here formula_17 is called lock-in frequency. Phase-locked loop ranges The terms hold-in range, pull-in range (acquisition range), and lock-in range are widely used by engineers for the concepts of frequency deviation ranges within which phase-locked loop-based
