  • Abstract To design an FIR filter, the Weighted Least Squares Method is a well-known method. And it has already been extended to design a variable fractional delay filter. It is presented that the efficiency is better than the method based on Lagrange interpolation. The weighting function is very important in the Weighted Least Squares method. Some authors have presented that if a suitable weighting function is used to design the filter, the Weighted Least Squares method can produce the quasi-equiripple result. In this paper, this ideal is extended to design a quasi-equiripple variable fractional delay FIR filter. The presented method is superior to the plain Weighted Least Squares design in the peak absolute error by about 6.7 dB.
