WebThe Farrow resampler block also has a complex mixer for composite carrier-frequencyoffset. The DPD subsystem circularly clips the data, and then applies nonlinear and linear correction. The GC5322 DPD block reduces adjacent-channelleakage ratio (ACLR), or out-of-bandenergy, by 20 dB or more. The efficiency of
WebFarrow 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 … 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. The output signal is approximated with a polynomial of degree M. The … See more

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.
WebFarrow filter resampler. The user-programmable Farrow resampler supports upsampling rates from 1× to 64×, with 16-bit precision on the interpolation ratio. It marks the transition of the input clock domain (driven by the input interface clock) to the transmit domain (driven by the DAC sampling clock).
