Phase estimation as applied to group delay measurements
Alan Paul Phillips · UA Campus Repository (The University of Arizona) · 1991
This thesis addresses the problem of measuring the group delay of a network with different frequencies at its input and output ports. Three distinct methods of measuring group delay are developed and their performance compared in a Monte Carlo analysis. Also considered is the problem of second order nonlinear distortion and its effect on measuring group delay. A method is developed to identify a specific second order nonlinear structure causing distortion. A nonlinear equalizer is then developed to cancel, or equalize, the undesired second order distortion.
