Document Type and Number:
WIPO Patent Application WO/2024/053539
Kind Code:
A1
Abstract:
This noise removal device (1) comprises: a noise detection unit (10) which detects noise having a frequency component across a band wider than a bandwidth of a desired signal included in an input signal; and an interpolation unit (20) which removes the detected noise from the input signal and interpolates the portion removed together with the noise of the input signal.
