Detailed Description

A resampling block using interpolator, halfband filter and NCO.

Resampling block This class uses an interpolator a halfband filter (for decimating by 2) and a NCO samples are input with each call to update, but output samples are available when the ready bit is set The halfband filter is a simple IIR filter based on two first order allpass filters. The interpolator is a Lagrange interpolating FIR
