NOISE ANALYSIS DEVICE, ELECTRONIC DEVICE, AND NOISE SOURCE SPECIFICATION SYSTEM

摘要

A noise analysis device is provided with a plurality of digital filters and a noise analysis unit. The digital filters have different filter characteristics, and filter the same input signal to output a plurality of output signals. The noise analysis unit detects the presence or the absence of noise in the input signal on the basis of the output signals. More specifically, the noise analysis unit detects the presence or the absence of noise in the input signal on the basis of whether or not the values of the output signals match.
