Dynamic Behavior of a System of Mutually Synchronized Oscillators

An analysis is presented of the performance of a synchronous digital communications system in which the clock rate of each station is established as the average of the clock rates of all incoming signals to each station. In a previous paper the steady-state frequencies and phase relationships between stations were analyzed. Here the dynamic response of various frequency-averaging system configurations are analyzed using a time-incremental computer simulation of the system. Plots of the instantaneous frequency and phase variations in response to transmission-path changes ate provided. The frequency and phase response predicted by the computer simulation was correlated against a laboratory breadboard model. Also, the final steadystate conditions predicted by the computer simulation are correlated against the steady-state changes predicted by the previous static final-value analysis.
