Wavelet Synthesis

Tree Structure
The wavelet tree structure has n+1 inputs, where n is the number of levels. The
sample rate and bandwidth of the output are twice the sample rate and
bandwidth of the top input. The sample rate and bandwidth of each additional
input (except the last) are half that of the input to the previous level.
The bottom two inputs (u
n
and u
n+1
) should have the same sample rate and
bandwidth since they are processed by the same level.
Note that in frame-based mode, the sample period of input u
k
is reflected by its
frame size, M
i,k
, rather than by its frame rate.
Sample-Based Operation
An M-by-N sample-based matrix input is treated as M∗N independent
channels, and the block filters each channel independently over time. The
output is the same size as the input at each port, one output channel for each
input channel. As described earlier, each input port has a different sample
period.
