# Block Diagram Reduction

*Edit***Block Diagram Reduction**. So, to reduce the block diagram, proper logic must be used. Three primary situations for reducing block diagrams to simpler forms: -series blocks -parallel blocks -"feedback" blocks.

Video Lecture on Block Diagram Reduction Techniques from Chapter Transfer Function, Block Diagram and Signal Flow Graph of Control Systems of EXTC, Electronics & Electrical Engineering. Let us try to simplify this using the rules described above, in order to get it into a more manageable form. Consider the system block diagram shown below.

### If you check Block reduction, Simulink. i am trying to simplify this systems block diagram.

Consider the system block diagram shown below.

Block Diagram Reduction: In many practical situations, the block diagram of a Single Input‐ Single Output, feedback control system may involve several feedback loops and summing points. Consider the block diagram shown in the following figure. Subsystems are represented in block diagrams as blocks, each representing a transfer function.
