Abstract
An apparatus for estimating a transfer function of at target object having divided systems is disclosed. The apparatus acquires an estimation equation to estimate the transfer function of the target object, and determines, for each arithmetic operation in the estimation equation, whether the arithmetic operation is an addition or a multiplication. For the multiplication, the apparatus performs the multiplication of frequency response characteristics in the frequency domain. For addition, the apparatus converts the frequency response characteristics into time response characteristics, performs the addition of the time response characteristics in the time domain, and reconverts a result of the addition into the frequency domain.
