Abstract :
In this paper, design of wide-range variable fractional-delay (WR-VFD) finite impulse response (FIR) digital filters is proposed and then is applied to implement comb filters. However, when it is applied to construct a variable comb filter which is an IIR system, stability constraint must be considered, and the technique of quadratic programming and a strategy of sampling points for stability constraint are used to design a stable variable comb filter.
