Signal Flow Graph

A node having only outgoing branches.

• Input node

• Output node

• Incoming node

• Outgoing node

A signal flow graph is the graphical representation of the relationships between the variables of set linear algebraic equations.

• True

• False

Use mason’s gain formula to find the transfer function of the given signal flow graph:

• abd/1-(ac)

• abdeg/1-(bc+ef)+bcef

• abd/1-(bc+ef)+bcef

• adcdef/1-(bc+ef)+bcef

Loop which do not possess any common node are said to be ___________ loops.

• Forward gain

• Touching loops

• Non touching loops

• Feedback gain

Signal flow graphs are reliable to find transfer function than block diagram reduction technique.

• True

• False

The relationship between an input and output variable of a signal flow graph is given by the net gain between the input and output node is known as the ______________

• Overall gain of the system

• Stability

• Bandwidth

• Speed

A feedback loop consisting of only one node is called as

• self loop

• individual loop

• non touching loop
