ABSTRACT:
Aspects of a sampling rate converter with no timing drift and with bounded amplitude error are presented. Aspects of the method may include computing an intermediate sum by adding a numerator portion of a fractional conversion ratio to an accumulated time value upon receipt of an input data sample. A time instant for generating an output data sample may be determined by computing a modulus value for the intermediate sum, wherein a base for the modulus value computing may be a denominator portion of the fractional conversion ratio.
