Question

4. E G > G. b) Given the block diagram as shown, R and D are inputs and G, G, and H, are transfer functions. a) Using only the block diagram reduction R с method*, find the transfer function C/R in terms of G, G, and Hz. H, Using only the block diagram reduction method*, find the transfer function E/D in terms of G, G,, and Hy c) Using either the block diagram reduction method* or the equation method, find the transfer function E/R in terms of G, G, and Hy. d) Using either the block diagram reduction method* or the equation method, find the transfer function C/D in terms of G, G, and H2 e) Identify clearly the characteristic function of the system. *NOTE: All stages of block diagram reduction must be clearly shown until you arrive at the last simple closed loop diagram and then the final open-loop equivalent with the transfer function in question. In addition, the final transfer function must be simplified, i.e., no fraction(s) over fraction(s).
