| Abstract(in English) | We are investigating countermeasure technique against electro-magnetic noise by using the method based on the linear predictive coding (LPC). We applied the method to the characterization of acoustic noise, and we developed a spectral analyzer which displays LPC spectrum. As the intensities of the peaks of LPC spectrum do not correspond to the intensity of electro-magnetic noise, some modifications were required. We developed modified LPC whose spectrum gives the intensity of given noise, and we show the method here. |
