本文从理论上证明了由非线性插值多项式导出的一维可变分数延迟(VFD)有限脉冲响应(FIR)数字滤波器系数的Liu-Wei封闭公式。在本文中,我们揭示了VFD滤波器系数的对称性,并利用系数对称性来评估VFD滤波器的频率特性,降低了计算复杂度。系数对称性也被利用在有效地实现VFD滤波器的Farrow结构和奇偶结构的高速信号处理
We have theoretically proved the Liu-Wei's closed-form formula for computing the coefficients of one-dimensional (1-D) variable fractional-delay (VFD) finite-impulse-response (FIR) digital filter derived from nonlinear interpolating polynomial. In this paper, we reveal the symmetry of the VFD filter coefficients and exploit the coefficient symmetry in evaluating the VFD filter frequency characteristics with reduced computational complexity. The coefficient symmetry is also exploited in efficiently implementing the VFD filter as Farrow structure and even-odd structure for high-speed signal processing
