摘要：
An improved algorithm is derived form minimising the global roundoff noise gain (G) over bar of nth-order digital filters, yielding at least n(n-1)/2 coefficients of the filter structure to be zero. This algorithm is based on the necessary and sufficient conditions for the minimum (G) over bar subject to the transformation matrix being triangular, and these conditions are achieved by modifying the Smith and Bomar iterative algorithm.
