  • Method and arrangement for sampling rate conversion
    Patent number: 8538713
    Abstract: Re-sampling of a signal represented by a plurality of input samples is described. An output sample value is calculated for a desired time instant, tD, between any two time instants of the input samples by performing a procedure that comprises selecting a current set of values from the input sample values. A new set of values is calculated by up-sampling the current set of values. A subset of values is selected from the calculated new set of values and the current set of values surrounding the desired time instant of the output sample value, whereupon the output sample value is calculated using at least one value of the selected subset of values. The calculation of a new set of values and the selection of a subset of values from the new set and the current set is iterated a specific number of times, wherein during the iteration the current set of values is set to the selected subset of values.
