Generate three connected ER graphs: G 1 (with edge probability of 0.2), G 2 (with edge prob- ability of 0.25), and G3 (with edge probability of 0.3), each having 50 nodes. Define three graph signals: f1 = u 0 on graph G 1 , f2 = u24 on graph G 2, and f3 = u49 on graph G 3. Now connect the three graphs by adding six additional edges to form a single connected graph G . Consider signal f = [ f1 T f2 T f3 T ] T on graph G

(a) Plot the GFT coefficients of signal

f. Do they convey any information about the local

frequency content of the signal f supported by graphs

G1,G2, andG3? Why or why not?

(b) Plot and explain the spectrogram of graph signal

f assuming a heat kernel g^(?`) = ae?k?`;

choose the constants a and k such that ||g||2 = 1.

_______ is not a reference type.

a. A class type b. An interface type c. An array type d. A primitive type
