20120021710 | ELECTROMAGNETIC WAVE DISCRIMINATION DEVICE, ELECTROMAGNETIC WAVE DISCRIMINATION METHOD, AND ELECTROMAGNETIC WAVE DISCRIMINATION PROGRAM - An electromagnetic wave discrimination device according to the present invention discriminates electromagnetic waves, and includes an acquisition section, a feature quantity calculation section, a similarity calculation section, a classification section, a discrimination section, an output section, and a storage section. The acquisition section receives communication signals of a predetermined frequency, and samples waveform data of the communication signals every predetermined time to obtain sample data for each predetermined time. The feature quantity calculation section calculates amplitude feature quantities for each predetermined time, based on the sampling data for each predetermined time. The similarity calculation section calculates degrees of similarity with respect to the amplitude feature quantities for each predetermined time. The classification section classifies the communication signals for each predetermined time into clusters to obtain cluster analysis results of the communication signals for each predetermined time, based on the degrees of similarity. The discrimination section discriminates communication signals constituting one cluster for each of the clusters to obtain discrimination results, based on the cluster analysis results of the communication signals for each predetermined time. The output section outputs the discrimination results. The storage section stores the amplitude feature quantities, the degrees of similarity, the cluster analysis results, and the discrimination results. | 01-26-2012 |
20120041730 | POWER-SUPPLY DESIGN SYSTEM, POWER-SUPPLY DESIGN METHOD, AND PROGRAM FOR POWER-SUPPLY DESIGN - Provided is a power-supply design system that supports a power-supply design by applying a random model based on an outline of an operation circuit of an electronic device to calculate a value representing a power-supply fluctuation with a statistical technique, and by outputting a statistical value representing the power-supply fluctuation.

20140043039 | IMPEDANCE MEASUREMENT SYSTEM, IMPEDANCE MEASUREMENT METHOD AND PROGRAM - A condition input device inputs a measurement condition and the information of an electronic apparatus to be measured. A measurement operation program device selects a program that causes the electronic apparatus to perform an measurement operation based on the information of a measuring target object and the measurement condition. A voltage measurement device measures a voltage variation generated by the power source of the electronic apparatus. A wave form calculating device performs an arithmetic processing, such as a filtering processing or a time-frequency conversion (e.g. Fourier conversion) for the measured voltage variation to obtain the frequency characteristics of the voltage variation. An impedance calculating device calculates an impedance from the frequency characteristics of the voltage variation and the frequency characteristics of current and the condition of the measurement operation program. | 02-13-2014 |
