Nonlinear response of PLL (Phase Locked Loops) occurs as a consequence of sinusoidal characteristics of phase detector, whereas each nonlinearity causes a distortion in response. This mode is not desirable and in it, in one part of frequency characteristics a large discontinuity occurs, known as a jump phenomenon. The area of the jump phenomenon and critical values of PLL parameter can be determined by analyzing frequency characteristics.
Keywords: PLL (Phase Locked Loops), jump phenomenon, nonlinear distortion, frequency characteristics.
