How Do I Solve a Block Diagram in Mathematica?
Wolfram Research offers a number of specialized packages for control design and analysis as well as for DSP design and code generation. Nevertheless, it is instructive to see how easily you can solve block diagrams using just the basic package. If you are interested in more-advanced packages, take a look at Control System Professional, Analog Insydes, or Signals and Systems in the Mathematica store. Reducing the Block Diagram and Computing the Closed-Loop Transfer Function Write a block diagram equation for the rightmost closed loop in the diagram, and solve for the input to this loop.
