ABSTRACT:
A sample rate converter for converting a digital input signal having a first sample rate into a digital output signal having a second sample rate, wherein the second sample rate is different from the first sample rate. The sample rate converter includes a digital interpolation filter receiving the input signal and comprising a digital zero-phase filter, and a digital polynom interpolator connected to the interpolation filter and providing the output signal.
