Abstract
One embodiment relates to an apparatus for sample rate conversion. A sample rate converter is arranged to receive an input signal at an input sampling frequency and use an interpolation interval to convert the input signal to an output signal at an output sampling frequency. A rate controller is arranged to alternate between different frequency control words for use in generating the interpolation interval signal. Another embodiment relates to a method of sample rate conversion. Another embodiment relates to a rate controller circuit. Other embodiments, aspects, and features are also disclosed.
