  • \$\begingroup\$ Write the signal expressions on each line until you get the output in terms of the input and the gains. Then see how you can simplify it and redraw. \$\endgroup\$ – Eugene Sh. Feb 23 '17 at 15:04

    \$\begingroup\$ It's not that complex. Don't be a baby. You've made a good start. repeat what you did for A/B with C/D and there's another step down the path. \$\endgroup\$ – Andy aka Feb 23 '17 at 15:07

  • \$\begingroup\$ Are you asking for a list of rules (can be found in each good book on control systems)? Or are you asking WHICH of this rules could be recommended? (There is always a number of different approaches). \$\endgroup\$ – LvW Feb 23 '17 at 15:46
