HDL Sample Rate Conversion Using Farrow Filters

WebJun 1, 2024 · In this work, instead of using M-polyphase components of a filter for differentiating the input signal, a small-order subfilter of the Farrow structure is proved to be sufficient. Farrow structure is known to function as a differentiator, which is used to realise interpolation in the signal processing sense [ 19 ]. Webfrc = dsp.FarrowRateConverter creates a polynomial filter-based sample rate converter System object, frc. For each channel of an input signal, frc converts the input sample rate to the output sample rate. frc = dsp.FarrowRateConverter (Name,Value) sets properties using one or more name-value pairs.
