Abstract
In this study, we considered a calculation method to obtain accurately transfer functions employed in running transfer path analysis, and tried to reduce noise influence effectively in transfer functions by setting probability significance level of each input signal as noise reduction standard. Next, we verified the noise reduction performance through simple simulation and compared that with the conventional method in which size of input signal was employed as the standard. As results, the noise influence was reduced from calculated transfer function by using the new method effectively better than that of the conventional method.
