Determine the system function, H(z), from x[n] to y[n] for the flow graph shown in Figure P6.28-1 (note that the location where the diagonal lines criss-cross is not a single node).

(b) Draw the direct form (I and II) flow graph of systems having the system function H(z).

(c) Design H₁(z) such that H₂(z) in Figure P6.28-2 has a causal stable inverse and |H₂(e^jω)| = |H(e^jω)|. Note: Zero-pole cancellation is permitted.

(d) Draw the transposed direct form II flow graph for H₂(z).
