Abstract
A noise analyzing apparatus includes an input unit for inputting a structure of an autonomous system, parameter values and analysis conditions, a periodic steady-state solution calculating unit for calculating a periodic steady-state solution of the autonomous system, a noise source adding unit for adding a noise source to a periodic linear time-variant system obtained by linearizing the autonomous system around the periodic steady-state solution, a time-variant transfer function calculating unit for calculating, for each noise source, a time-variant transfer function of the periodic linear time-variant system to which noise sources are added, a reflected component calculating unit for adding power of a time-variant transfer function reflected to a frequency to be observed, and an output unit for outputting as a result of analysis relating to noise based on results of calculations by the above-described calculating units.
