%
% FastATROUSynthesis -- Fast Inverse Dyadic Wavelet Transform
%  Usage
%    s = FastATROUSynthesis(dwt,L)
%  Inputs
%    dwt  strcture array
%    L    Coarsest Level of V_0;  L << J
%  Outputs
%    s	original 1-d signal; length(x) = 2^J = n
%  Description
%    1. filters are obtained with MakeATrouFilter
%    2. usually, length(qmf) < 2^(L+1)
%    3. The transformed signal can be obtained by FastATROUAnalysis
