Abstract(in English) | This paper presents efficient quantization method for coefficients using a GA and an SA. When digital filters are realized, their coefficients need to be quantized, so that computational circuits and registers are constructed with limited word length. Therefore the characteristic of the digital filter which is actually realized and used is different from its characteristic theoretically obtained. In order to improve such a decayed characteristic, the method with a GA and an SA has been proposed. In this paper, we improve the design of GA and SA and thereby the filter coefficients which give smaller decay can be obtained. Several experiments show the efficiency of our proposed method. Furthermore, the other experiment indicates that the proposed method is independent of types of filters and quantization intervals of coefficients. |
