WebJun 2, 2016 · One allpass filter that might be acceptable (if the sinusoid frequency is relatively slow) and would certainly be simpler would be a variable delay. If you needed a phase shift at a finer granularity than a single sample, then you could achieve this through a fractional interpolation filter. For example, look at the Farrow Structure. WebA Farrow filter uses polynomial approximation to replace a conventional resampling filter, such that the approximation is done section by section. Commonly used Farrow filters interpolate neighboring sample points via cubic or parabolic interpolation. However, if the application has a strict requirement on the filter response, approximations ...
