A class of Farrow-structure-based reconfigurable bandpass finite-length impulse response (FIR) filters for integer sampling rate conversion is introduced. The converters are realized in terms of a number of fixed linear-phase FIR subfilters and two sets of reconfigurable multipliers that determine the passband location and conversion factor, respectively. Both Mth-band and general FIR filters can be realized, and the filters work equally well for any integer factor and passband location. Design examples are included demonstrating their efficiency compared to modulated regular filters. In addition, in contrast to regular filters, the proposed ones have considerably fewer filter coefficients that need to be determined in the filter design process.
