This paper introduces a new structure for reconfigurable two-stage finite-length impulse response (FIR) Nyquist filters using the Farrow structure. The Nyquist filter is split into two equal and linear-phase FIR spectral factors. In the first stage, the Farrow structure realizes reconfigurable lowpass linear-phase FIR interpolation/decimation filters whereas the second stage is composed of a fixed lowpass linear-phase FIR filter. By adjusting the variable multipliers of the Farrow structure, the overall filter can be modified. Hence, various FIR Nyquist filters and integer interpolation/decimation structures are obtained. However, the filter design problem is solved only once and offline. Design examples illustrate the method.
