Abstract

A sample rate converter for converting the sampling frequency of an input signal from a first frequency to a second frequency. Such a sample rate converter uses interpolation means and a phase locked loop receiving the first and the second sampling frequency. The invention provides a sample rate converter which uses interpolation means implemented as polynomial interpolation means.
