Question - 2. (50 points) A causal LTI system has the signal flow graph shown in Fig. 2. Answer the following related questions, yin] x[n] Fig. 2 a) If the above system is known to be FIR, determine the value of A and the difference equation b) If the value of A is known to be - 5 (i.e., A = -5), determine the system function H(z). c) Draw the transposed direct form II signal flow graph implementation of the above system using the results obtained from part (b). (Answer this part for A = -5.) d) Which signal flow graph is better for implementation (the one in Fig. 2, or the transposed direct form II flow graph obtained in part-c, or either)? You must justify your answer in terms of number of multipliers and shift registers.
