Exempel på hur man kan använda SUBBAND i en mening

• The process of decomposition performed by the filter bank is called analysis (meaning analysis of the signal in terms of its components in each sub-band); the output of analysis is referred to as a subband signal with as many subbands as there are filters in the filter bank.
• Originally known as optimal subband tree structuring (SB-TS), also called wavelet packet decomposition (WPD; sometimes known as just wavelet packets or subband tree), is a wavelet transform where the discrete-time (sampled) signal is passed through more filters than the discrete wavelet transform (DWT).
• After that is the implementation of SWT, its purpose is to mitigate the information loss produced by the downsampling in each DWT subband.
• If all N steady-state rate equations are summed, the right hand side becomes zero, meaning that the system is underdetermined, and it is possible only to find the relative population of each subband.
• One subband may allow CW or RTTY whereas other subbands may be designated for telephony or image communications.
• The contourlet transform has a fast implementation based on a Laplacian pyramid decomposition followed by directional filterbanks applied on each bandpass subband.
• The decoder has to perform the reverse process, that is, demultiplex and decode each subband of the bitstream and recombine them.
• The first multiscale speckle reduction methods were based on the thresholding of detail subband coefficients.
