  • Patent number: 11973584
    Abstract: This application relates to a noise signal generating apparatus. In one aspect, the apparatus includes a bandwidth expansion unit configured to generate a noise signal having a second bandwidth by expanding a noise source signal having a first bandwidth to the second bandwidth that is greater than the first bandwidth. The apparatus may also include a randomization unit configured to perform randomization and output the generated noise signal having the second bandwidth.
