Description

The code above creates a block diagram using the TikZ package in LaTeX. The diagram includes several components, including an input node labeled "A", a computation node labeled "B", a block node labeled "C" with the transfer function $K\frac{s+1}{s+5}$, another block node labeled "D" with the transfer function $\frac{2}{s^2(s+2)}$, and an output node labeled "E". There are also several links between these components, including a link labeled "$R(s)$" from node A to node B, a link from node B to node C, a link from node C to node D, and a link labeled "$C(s)$" from node D to node E. Finally, there is a return link from the output node E to the computation node B.
