WebThis example shows how to design digital fractional delay filters that are implemented using Farrow structures. Digital fractional delay filters are useful tools to fine-tune the sampling instants of signals. They are for example typically found in the synchronization of digital modems where the delay parameter varies over time. WebThis code snippet provides a Matlab / Octave implementation. And here is the same in C, with explicit sample-per-sample calculation that allows varying the output rate even during operation (the Matlab version is vectorized). Background. A Farrow structure resamples a signal at an arbitrary, possibly time-varying sampling rate.
