Consider the eight-point decimation-in-time (DIT) flow graph in Fig. 6.6.
(a) What is the gain of the "signal path" that goes from x(7) to X(2)7
(b) How many paths lead from the input to a given output sample? Is this true for every output sample? (c) Compute X (3) using the operations dictated by this flow graph.
