The ideal fractional delay filter is a linear phase allpass filter. Its impulse response is a time-shifted discrete sinc function that corresponds to a non causal filter. Since the impulse response is infinite, it cannot be made causal by a finite shift in time. It is therefore non realizable and must be approximated.

A slow-light medium based on multiple, closely spaced gain lines is studied. The spacings and relative strengths of the gain lines are optimized by using the criteria of gain penalty and eye-opening penalty to maximize the fractional delay defined in terms of the best decision time for random pulse trains. Uniform bounded input bounded output stability of fractional‐order delay nonlinear systems with input.

Feb 23, 2019 · The delay in samples can be split up into whole samples and the fractional part. E.g. 2.3 into a sample delay with t_d = 2 samples and a fractional delay with t_fd = 0.3 samples. We agree, if the fractional part is zero, we have only a sample delay. So there’s of course no change in magnitude response.

A linearly interpolated delay line is depicted in Fig.4.1.In contrast to Eq.(), we interpolate linearly between times and , and is called the fractional delay in samples.The first-order (linear-interpolating) filter following the delay line in Fig.4.1 may be called a fractional delay filter [].Equation (), on the other hand, expresses the more general case of an interpolated table.
