Systems in SeriesSystems in ParallelState Space ModelAdders and MultipliersSimplifying Block DiagramsWhen two or more systems are in series, they can be combined into a single representative system, with a transfer function that is the product of the individual systems we have two systems, f(t) and g(t), we can put them in series with one another so that the output of system f(t) is the input to system g(t). Now, we can analyze them depending on whether we are using our classical or modern methods we define the oSee more on enbooks

What do the Different Flowchart Shapes Mean?
Summing Junction This shape adds the inputs. To subtract, you add a negative input. Logical Or This shape performs a logical Or on the inputs. If the inputs are A and B, the output could be A or B. Flowchart Key: Over the years other shapes have been used in flowcharting, but they have not been popular.

PDF fileIf a block diagram has many blocks, not all of which are in cascade, then it is useful to have rules for rearranging the diagram such that you end up with only one block. For example, we would want to transform the following diagram Moving a summing point ahead of a block 6.
