An interpolator, method of interpolating a one-bit signal and resampler employing
the interpolator and method. The interpolator employs a cascaded architecture to
interpolate a one-bit input signal received at an input thereof. In one embodiment,
the interpolator includes a multiple order interpolation filter that generates
a sample range from at least three input samples associated with the one-bit input
signal. The interpolator further includes a linear interpolation filter, associated
with the multiple order interpolation filter, that develops a plurality of samples
within the sample range.
