(That is, you Following the same logic, we can write the formula for 3 circles Venn diagram: n(A ∪ B ∪ C) = n(A) + n(B) + n(C) – n(A ∩ B) – n(B ∩ C) – n(C ∩ A) + n(A ∩ B ∩ C), Venn Diagram Examples (Problems with Solutions). Then eliminating two loops results in Figure 3-43(b). Control System Problems: Formulas, Solutions, and Simulation Tools Next we apply transformations 1 and 3 to the loop that contains the transfer function as feedback and get the following block diagram: X(s) H3(s) Similarly, by applying transforms 1 and 3 we obtain the simplified block dia- gram that represents the system's transfer function. d) Answer Message msg2 is sent after msg1 has been received.
