Homework Help: Signals and Systems: Deriving differential equation from block diagram

  1. Sep 29, 2009 #1
    1. The problem statement, all variables and given/known data
    Consider the block diagram below. Find the differential equation of the system.

    2. Relevant equations
    None, other than understanding how block diagrams work.

    3. The attempt at a solution
    My attempt is posted below, as an image. The reason I am having such trouble is because I can only express things in terms of the signal node I have labeled 'd'. Ideally, I should be able to find an expression just involving y(t) and x(t), and their derivatives/integrals.
