This paper considers behaviors of first and second order phase-locked loops (PLLs) and delay-locked loops (DLLs) in the presence of interfering signals. In the first part sufficient asynchronous conditions of the PLL with a rectangular signal and of the DLL with a pseudo random signal in the presence of the interfering signals are obtained using a simplified method devised by the author. Fluctuation of phase difference between signal and output of voltage controlled oscillator caused by the interfering signal is also analyzed by the method in the second part. By this method one can compare the interfering effects on several types of signals and get informations about the selection of appropriate signals.
