Consider the discrete-time linear causal system defined by the difference equation 1 3 1 y[n]y[n 1] + y[n- 2] − y[n - 8 2] = x[n] + x[n] + x[n - 1] 3 Draw a signal flow graph to implement this system in each of the following forms: c) Direct form I. d) Direct form II. e) Cascade. f) Parallel. For the cascade and parallel forms use only first-order sections.
