| Abstract(in English) | Evaluation on electromagnetic noise is usually evaluated in frequency-domain, as modulation and demodulation are realized based on Fourier-theory. However, frequency-spectrum must be induced by setting band-width in frequency on signals, by the reason that frequency-spectrum analysis techniques have uncertainty between frequency domain and time domain. However, in case that frequency-resolution is not enough, we have a problem that measured spectrum are different everytime spectrum measurement is implemented. In this paper, by analyzing the limitation of a various kinds of spectrum analysis techniques, authors describes the necessity of application of statistical method in order to evaluate electro-magnetic noise in frequency-domain and propose a noise evaluation technique by obtaining and utilizing the probability-distribution of noise in a frequency band. |
