Abstract:
1. Device for polyphase resampling, provided with a coefficient generator which provides a plurality of coefficients; at least one interpolation circuit provided in the coefficient generator in order to generate coefficients from constant coefficients; an interpolation arrangement for the realization of resampling by means of the coefficients based on input data to provide output data submitted for resampling wherein the coefficient generator is constructed and/or controlled in order to provide coefficients for the resampling as linearly interpolated coefficients; at least two multiplexers for multiplexing of a first coefficient sequence of coefficients at two inputs, respectively, of one of the interpolation circuits; and a phase accumulator to provide one phase value out of a plurality of bits; wherein the most significant bit in the plurality of the bits is input to the multiplexers in order to control these multiplexers, and the least significant bits in the plurality of the bits are input to the interpolation circuits.
