Abstract : An approximate analysis is made of phase-lock loop false locks as determined by the gain-phase characteristics of the phase-lock loop. The solutions presented enable the calculation of the false-lock frequencies if the open-loop phase characteristic is known. A simple design criterion is suggested to permit the design of a loop with no stable locks other than the desired lock frequency.
