Document Type and Number:
WIPO Patent Application WO/2024/053540
Kind Code:
A1
Abstract:
A noise elimination device (1) comprises: a noise detection unit (10) that detects noise having a frequency component spread across a band wider than the bandwidth of a desired signal included in an input signal; an FFT unit (51) that detects the frequency spectrum of a signal corresponding to the detected noise; and a noise elimination unit (60) that determines noise to be eliminated by comparing the frequency spectrum of the input signal and the frequency spectrum of the signal corresponding to the detected noise, and eliminates, from the input signal, the noise to be eliminated which was determined.
