Description

The code above creates a block diagram using the TikZ package. It defines several block components using the "blox" package, including an input (labeled "A"), a computation block (labeled "B"), a block for a transfer function with the label "G(s)", an output block (labeled "E"), and a return block. It connects these blocks with arrows labeled with either transfer functions or block names. The diagram represents a feedback control system with an input labeled "R(s)", a transfer function "G(s)", and an output labeled "C(s)". The return block connects the output of the system back to the input of the computation block, forming a closed loop.
