Which of the following statements about the signal flow graph of control systems is INCORRECT?
1
The transfer function is referred to as transmittance in a signal flow graph.
2
The representation of equation y = Kx, is represented by a signal flow graph as
3
It is a further simplification the of K-graph of a control system.
4
The blocks of transfer function, summing symbols and take off points are eliminated by branches and nodes in this graph.
5
Each branch has an associated gain and direction, signal can flow only in the direction of the arrow.
