1. A system for performing sample rate conversion and creating fractional delays to a signal, the system comprising: a filter; a look up table for storing coefficients for sample rate conversion and fractional delays, wherein the coefficients stored in the look up table comprise the coefficients required to generate delays in desired increments of a sample rate; control circuitry configured to use an indexing scheme to select one or more coefficients from the look up table for rate conversion and fractional delays, wherein the one or more coefficients necessary for a desired sample rate and fractional delay are selected from a single look up table.
