WebFarrow resampler implementation. Farrow resampler implementation in C, including optional bank switching. The functionality is mainly identical to the matlab code snippet. A discussion of the optional bank switching variant (which may require fewer multiplications per output sample for a given signal quality) can be found in my blog entry. To compute the output of a fractional delay filter, we need to estimate the values of the input signal between the existing discrete-time samples. Special interpolation filters can be used to compute new sample values at arbitrary points. Among those, polynomial-based filters are of particular interest because a … See more The ideal fractional delay filter is a linear phase allpass filter. Its impulse response is a time-shifted discrete sinc function that corresponds to a non … See more The advantage of the Farrow structure over a Direct-Form FIR resides in its tunability. In many practical applications, the delay is time-varying. For each new delay we would need a new set of coefficients in the … See more Lagrange interpolation is a time-domain approach that leads to a special case of polynomial-based filters.
