  • Alias-free subband processing
    Patent number: 9754597
    Abstract: A digital signal is processed by splitting it into at least two frequency subbands and the two subband signals are downsampled. A filter is applied in at least one of the subband signals. At least one of the phase and magnitude of the subband filtered signals is matched in the transition frequency band between the two subbands.
    Type: Grant
    Filed: November 3, 2016
    Date of Patent: September 5, 2017
    Assignee: Creative Technology Ltd
    Inventors: Jean-Marc Jot, Martin Walsh, Jean Laroche, Mark Phillips, Michael Chorn, Michael M. Goodwin
