<div class="textblock"><p>Compute intermediate samples between signal samples x(k*Ts)</p>
<p>This implements a Mininum Mean Squared Error interpolator with 8 taps. It is suitable for signals where the bandwidth of interest B = 1/(4*Ts) Where Ts is the time between samples. </p>
<p>Although mu, the fractional delay, is specified as a float, it is actually quantized. 0.0 <= mu <= 1.0. That is, mu is quantized in the interpolate method to 32nd's of a sample. </p>
