FractionalDelayV2Fract32

Overview

Provides fractional delay

Discussion

This subsystem implements a delay module which provides a fractional delay. This can be achieved by cacading the delay module and a fir filter which is designed to provide the fractional delay of 0.0to 1.0. Filter will have own set of coefficients for each fractional value which are calculated at design time.
