Description

The code above is a LaTeX code for creating a block diagram using the blox and tikz packages. The block diagram represents a control system with a single input, $R(s)$, and a single output, $C(s)$. The system is represented by a single block labeled C, with transfer function $\frac{G\_3(G\_2+H\_1)}{1+G\_2H\_2+H\_3G\_3(G\_2+H\_1)}$, and with input connected to the input A and output connected to the output E. There are also labels for the input and output signals, with $R(s) \quad $ representing the input signal and $\quad C(s)$ representing the output signal. The packages amsmath and amssymb are included for typesetting math equations. The standalone document class is used to create a standalone image of the block diagram.
