Abstract

JONES:DSD1) (C+, C-, C0) designs are known to prevent two-factor product terms and squared terms from confounding linear terms. However, the number of experiments required is roughly twice that of the conference (C) matrices alone. Therefore, when comparing the DSD design with the C matrices and [a,b] analysis2) using the same layout (Power supply3) circuit: 3 levels, 6 factors), the number of experiments was roughly the same. The response (output voltage: larger is better) characteristics were 21.11 and 31.69, respectively, and the latter (C matrices and [a, b] analysis) was superior, so we report this. Furthermore, the level combination response for the maximum factor effect of DSD was below the maximum value of the DSD response.
