Assuming that the underlying structure for the input signal f is a bipartite graph, plot the kernels in the spectral domain for the filters H 1 , G 0, and G 1 so that perfect reconstruction condition is satisfied. Considering a signal f = [ ? 2 , 1 , 9 , 0 , 4 , ?5] T defined on the graph G shown in Figure 11.5(a), find the signals at the output of each block in Figure 11.10 and verify that perfect reconstruc- tion is achieved.
