Consider a causal linear time-invariant system whose system function is

1- (1 - :- + -) (1 + -1)* H(2) :

(a) Draw the signal flow graphs for implementations of the system in each of the following forms:

(i) Direct form I

(ii) Direct form II

(iii) Cascade form using first-and second-order direct form II sections

(iv) Parallel form using first-and second-order direct form II sections

(v) Transposed direct form II

(b) Write the difference equations for the flow graph of (v) in part (a), and show that this system has the correct systemfunction.
