Patent abstract
Described herein is a method and system for sampling rate conversion. A clamped cubic spline interpolator (CCSI) may be utilized to interpolate or decimate a source signal to provide samples at times based on a sink rate. The source clock and sink clock may be driven by independent oscillators, and may therefore drift independently. A rate tracking algorithm may monitor the relative drift and adjust the conversion of the source signal to track the sink rate.
