Test: Signal Flow Graphs - 1 - Question 1

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

Detailed Solution for Test: Signal Flow Graphs - 1 - Question 1

Explanation: By definition signal flow graphs are the graphical representation of the relationships between the variables of set linear algebraic equations.

Test: Signal Flow Graphs - 1 - Question 2

A node having only outgoing branches.

Detailed Solution for Test: Signal Flow Graphs - 1 - Question 2

Explanation: Nodes are the point by which the branches are outgoing or ingoing and this can be input or output node and input node is the node having only outgoing branches.

Test: Signal Flow Graphs - 1 - Question 3

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

Detailed Solution for Test: Signal Flow Graphs - 1 - Question 3

Explanation: Using mason’s gain formula transfer function from signal flow graph can be calculated which relates the forward path gain to the various paths and loops.

Test: Signal Flow Graphs - 1 - Question 4
