This problem is about quantifying spread of a graph signal. The spread of a graph signal can be defined in the vertex as well as the spectral domains. In the vertex domain, the spread of a signal f lying on a graph G about a node v i is defined as

Based on the graph and spectral spread definitions, answer the following:



(a) Prove that







where ˆf(?`) is the GFT coefficient at frequency ?



(b) Write an expression for spectral spread of the eigenvectors of the graph Laplacian. What



is the relation between the spread of the eigenvectors?



(c) For the graph shown in Figure 11.1, find graph spreads of the eignevectors of the Lapla-
