本文提出了一种新的灵敏度准则，用于将真实的系数逼近到它们的二次幂。该方法将整个频率范围内的所有搜索点视为一种度量，以指示系数对频率响应的影响，而不是仅使用极值。该技术被证明是非常合适的无乘法器FIR滤波器的设计，几乎没有增加的计算时间。
A new sensitivity criterion for approximating real coefficients to their nearest powers of two is presented. The approach considers all searched points over the entire frequency range as a measure to indicate the impact of the coefficient on the frequency response as opposed to using the extremes only. The technique proved to be highly appropriate for the design of multiplierless FIR filters with virtually no increase in the computation time.
