Abstract
Method and apparatus for implementing a digital filter employing coefficients expressed as sums of 2 to an integer power. Coefficients expressed as sums of powers of 2 may be algebraically manipulated such that higher order terms are replaced by an equivalent group of lower order terms. In the context of a shift-and-add algorithm, the lower order terms require fewer shifting operations and less total hardware to effect multiplication than the corresponding higher order terms.
