摘要：

This brief examines the approximation of fractional delays by FIR systems using various techniques which have previously been reported in the literature. In particular, the equivalence of the time-domain Lagrangian interpolation, the frequency-domain maximally flat error criterion and the window method is shown, provided maximal flatness is specified at omega(0) = 0 and the window used is a scaled binomial function. The first of these has been known before, the second equivalence is new.
