ABSTRACT:
A digital FIR filter for producing an L phase interpolation of a input sample ##STR1## based on L filter banks and n tap coefficients P.sub.1 (i) in each 1.sup.th one of the filter banks is disclosed, where 1.ltoreq.1.ltoreq.L and where 0.ltoreq.i.ltoreq.(n-1). The digital filter includes a first circuit for producing, for each time t, bank filter terms of a merged bank filter having an output value which changes between a previous time t-1 and the time t. The produced bank filter terms include at least one combination of two cross-symmetric bank filter terms:
