Abstract
The present disclosure provides a method and system for combining multiple coefficient words using only the magnitude bits of each of the coefficient words and using the sign bits of each of the coefficient words to modify the output of the combined magnitude bits. Using this method and/or system, it is possible to implement, for example, digital filters using larger coefficient word sizes without having to incur the inefficiencies and cost associated with using additional hardware resources, while maintaining an acceptable gain error in the filter response.
