| Abstract: | In this paper, the root locus of third and fourth order differential controlled phase locked loop discriminator are analyzed. By means of computer aided analysis and theoretical research, under different time constant conditions, the boundary value of parameter to cause abrupt change of root locus of fourth order phase locked loop is determined. It provides a useful basis for the study and design of the time performance of transient response of such a phase locked loop discriminator with lower threshold. |
