The frequency sampling design technique is applied in the design of fractional-delay root-Nyquist filters. Comparisons are made with three alternative design styles, showing that favourable frequency sampling selections easily outperform these contenders with respect to composite impulse response zero-crossing errors and approach the quality provided by purpose-optimised alternatives.
