Abstract:
1. In a communication system, apparatus for transporting a plurality of sampled signals asynchronously from a first location to a second location comprising in combination: a source of one or more data signals and one or more clock signals at said first location; a plurality of reference clocks generating a plurality of reference signals at said first location; a phase difference estimator generating a phase signal representing at least an estimate of the difference in phase between one of said clock signals and a plurality of said reference signals; a communication channel transmitting said one or more data signals and said phase signal asynchronously to said second location; a resample filter located at said second location; a selector responsive to said phase signal for conditioning the resample filter in response to said phase signal, said conditioned resample filter being responsive to said one or more data signals for generating one or more resampled data signals at the second location; wherein the resampled data signals are accurately represent the original data signals without significantly burdening the communication channel with synchronization data.
