  • Process and device for segmentation into sub-bands and for reconstruction of a digital signal, and corresponding device
    Patent number: 5610944
    Abstract: A process and device for segmentation into and reconstruction from sub-bands of a digital signal each sample of which are submitted to a parallel processing on a plurality of paths by prototype filtering modulated by a periodic function and sub-sampling by the number of sub-bands. A combination of a filtering of modified polyphase type and of a processing by frequency transform is therefor performed so as to deliver a sub-band signal for each path of corresponding rank. Reconstruction comprises in combination the dual steps of frequency transform and modified polyphase filtering so as to deliver a reconstructed digital signal. Corresponding modules for frequency transform and modifyed polyphase filtering are embodied through MOT or PRMF filters.
