DIGITAL FILTER DESIGNING METHOD AND DESIGNING APPARATUS, DIGITAL FILTER DESIGNING PROGRAM, AND DIGITAL FILTER

摘要

One or more unit filters are prepared from basic unit filters having a predetermined basic numerical string h1 to h6 as filter coefficients. A digital filter is designed by combining these. Thus, by combining the unit filters, it is possible to automatically calculate a complicated filter coefficient, so that an engineer having no long experience can easily design filters.
