Delay discrete-time input by the time-varying fractional number of sample periods specified by the 'Delay' input. The input delay is clipped to a valid range (Dmin to Dmax) that is determined by the parameter settings. The block provides Linear, FIR, and Farrow interpolation modes. In FIR mode, the filter is designed using the 'firnyquist' function when Bandwidth value is 1, and 'intfilt' function from the Signal Processing Toolbox when Bandwidth is smaller than 1.
