ABSTRACT:
A methods and devices for polyphase resampling are presented which may comprise a coefficient generator which provides a plurality of coefficients and an interpolation arrangement used to carry out the resampling by means of the coefficients applied to input data provided for resampling in order to provide output data. In one possible implementation the coefficient generator is constructed and/or controlled so as to provide the coefficients for the resampling in the form of linearly interpolated coefficients. In another alternative implementation, a plurality of at least two data interpolation filters are provided for the interpolation of a corresponding number of parallel input data, wherein the coefficients are input to each of the data interpolation filters.
