Linear expansion based sine generator

摘要

An apparatus and method for generating a sine wave signal for a desired phase input. The sine wave signal is generated by implementing a linear expansion of the sine function. An incoming phase value is divided into a base phase value and an incremental phase value. The sine value for each base phase value is stored in a look-up table. The sine values for phase values falling between base phase values are generated using a linear expansion of the sine function.
