The dynamics of phase locked loops have been studied by many investigators for the cases of either a pure sinusoidal signal or for pseudo noise PN sequence. This dissertation presents an analysis of a phase locked system consisting of sinusoidal carrier modulated with a PN sequence. The effect of the modulation index of the phase shift modulation and the design of a loop filter for coherent detection of a PN sequence are analysed. Additionally, the error probability for each digit, when a likelihood detector is used in front of the delay lock discriminator for a PN sequence, is also converted to delay error of the phase lock loop.
