A sampled data interpolator includes a linear interpolator (20,24) coupled in parallel with a nonlinear compensation signal path (22,34). The nonlinearly processed signals and the linearly interpolated signals are summed (36) to produce interpolated samples. The nonlinear compensation signal path includes a finite impulse response filter (22) having tap weights conforming to a sinc function, and a weighting circuit for scaling filtered samples by a normalized sinc function. <IMAGE> |
