内容記述 | The weighted Chebyshev method proposed by Rabiner, Mclellan and Parks is well known as a useful method for the design of linear phase FIR (Finite Impulse Response) digital filters. However, the filters designed with this method are not always the maximal ripple filters. This paper presents an evaluation of FIR filters using the wave moments and how to find easily the maximal ripple filters. Herrman and Schuesssler proposed a method (HS method) to transform equiripple linear phase filters into an equiripple minimum phase filters with half the degree and the magnitude characteristic equal to the square root of the prototype. However, this method is limited by a numerical complexity. The HS method has been improved and used. But the filters are not always an equiripple in a passband. In this paper, we define the equiripple scale (Er) in a measure of the ripple. And we show the relation between Er and linear phase FIR filters as prototypes in the design of minimum phase filters. | |||||
