Abstract (in Japanese) (See Japanese page) 
(in English) Since the frequency and amplitude of radio noise generated by IT equipment fluctuate with time, it is difficult to
express the radio noise in the frequency domain. On the other hand, although it is possible to express the behavior of the radio noise in the time domain, its characteristics become unclear. In order to solve this problem, this paper examines a radio noise model that employs a mixed expression in the time and frequency domains. This model is inspired by the method, which has been conventionally used as an EMC measurement, of listening to sound the radio noise as a signal modulated wave with amplitude modulation or hase/frequency modulation. It is confirmed through comparison between the actual radio noise of notebook PCs and microwave ovens and its modelling result that the features of the radio noise can be expressed.
