System, Device, Method, and Program for Analysis
11 Aug 22
An analysis system includes inference processer circuitry configured to infer a corresponding classification by inputting part of frequency spectrum data corresponding to reference measurement data to a learned model having learned a relation between part of frequency spectrum data corresponding to sample measurement data and a classification related to noise corresponding to the part, causal component identification processer circuitry configured to identify causal component data of noise from a component data list based on the inferred classification, and a presentation information generator configured to generate presentation information for a user based on the causal component data.

Utility
Spectrum analysis method and spectrum analysis apparatus
8 Mar 22
Provided is a spectrum analysis method including: accumulating n spectrums obtained by consecutively fast Fourier transforming an input signal n times; receiving a threshold; identifying, in the n spectrums accumulated in the accumulating, frequently occurring data that includes data whose number of occurrences exceeds the threshold received in the receiving, the number of occurrences being defined as a total number of items of data at a same frequency point that indicate levels that are close to each other, to within a predetermined range; selecting a maximum level at each of the frequency points from among only the identified frequently occurring data; and outputting a spectrum indicating the maximum levels selected at the frequency points.

Radiated emission measurement method and radiated emission measurement system
16 Nov 21
A radiated emission measurement method includes a prescan measurement step of performing broadband measurement including detection of a peak and detection of a quasi-peak by one fast Fourier transform in a target measurement frequency range; a calculation step of calculating a difference in level between the peak and the quasi-peak obtained for a measurement frequency to be a candidate for a result of measurement; a determination step of determining whether the obtained difference is less than a reference value; and an output step of outputting a result obtained as an interference level of the radiated emission in the broadband measurement when it is determined that the difference is less than reference value, and performing narrowband measurement and outputting the obtained result as the interference level of the radiated emission, when it is determined that the difference is equal to or higher than the reference value.
