Consider an all-pass system whose system function is?

(a) Draw the direct from I signal flow graph for the system. How many delays and multipliers do you need? (Do not count multiplying by ? 1.)

(b) Draw a signal flow graph for the system that uses one multiplier. Minimize the number of delays.

(c) Now consider another all-pass system whose system function is

?Find and draw a signal flow graph for the system with two multipliers and three delays.?
