Inventor: PETER GRAHAM CRAVEN
IPC: H03H17/04
Filed: 2021-08-17
Abstract: To provide a method and a device for lossless band splitting and band joining of a stream of a signal sample using all-pass filtering.SOLUTION: A band split operation reformats the original stream into two intermediate streams that represent even and odd samples of the original stream, and then the matrix filters the two intermediate streams to provide two output substreams that represent the high and low frequency components of the original stream. Conversely, the band join arithmetic matrix filters two subband streams to provide two quantized intermediate substreams, and then provide the output stream by interleaving the filtered stream, and the intermediate substreams are even and odd samples of the output stream.SELECTED DRAWING: Figure 7
