A system for changing the sample rate of a digital signal precisely such that frequency coherence is maintained. The system uses coupled direct digital synthesizers to establish the phase of a resampled clock compared to the original clock. The system implements precision resampling that changes the sample rate of a sampled data signal, while maintaining the frequency coherence of the sampled signal. A precision phase calculation for the relation between an input clock and an output clock enables the precision resampling.
