Draw the SFG for the block diagrams in problem 2 then find the transfer function for both systems. In converting the block diagrams to a signal flow graph, observe the followings: 1- select the signal flow graph variables according to the following rules: a. input and output variables are SFG variables b. Output variables of Summers are SFG variables c. Input variables of blocks are SFG variables 2- Use the block diagram connection to write the causality relations of the SFG 3- When drawing the SFG from its causality relations, leave the variables (nodes) on the same location on the block diagram Find the transfer functions for the following block diagrams using block diagram reduction: R(s) Y(s) G, G, G, H, G G, H H G.
