| 1. An apparatus for sample rate conversion, comprising:
an interpolator configured to interpolate a digital input data stream having a first sample rate using values of an interpolation
phase shift control quantity to generate a digital output data stream having a second sample rate;
a computing stage configured to compute values of the interpolation phase shift control quantity; and
an enabling/disabling stage configured to selectively disable the interpolator while keeping the computing stage enabled.
