Abstract:
A digital filter for interpolation or decimation and a device incorporating the digital filter is disclosed. The digital filter includes a filter block, a first transformation circuit coupled to the filter block and an input stream coupled to provide input values to a component selected from the filter block and the first transformation circuit. The filter block includes a pair of sub-filters having respective transformed coefficients, the respective transformed coefficients of a first sub-filter of the pair of sub-filters being symmetric and the respective transformed coefficients of a second sub-filter of the pair of sub-filters being anti-symmetric. The first transformation circuit is coupled to perform a first transformation; the filter block and the first transformation circuit together provide suppression of undesired spectral images in final outputs of the digital filter.

Claim (Index 7):
An electronic device comprising:\n a digital up-converter, the up-converter comprising: a digital interpolation filter for interpolating by M, where M is an integer, the digital interpolation filter comprising:\n a filter block comprising a pair of sub-filters having respective transformed coefficients, the respective transformed coefficients of a first sub-filter of the pair of sub-filters being symmetric and the respective transformed coefficients of a second sub-filter of the pair of sub-filters being anti-symmetric, \n delay elements coupled to provide input values to the filter block, and \n a first transformation circuit coupled to receive intermediate outputs from the filter block and to perform a first transformation on the intermediate outputs to form final outputs of the pair of sub-filters, the filter block and the first transformation circuit together providing suppression of undesired spectral images in final outputs of the digital interpolation filter; and \n a digital-to-analog converter coupled to receive the final outputs of the digital interpolation filter and to provide an analog output signal.
