Consider the following statements for signal flow graph: 1. It represents linear as well as non-linear systems. 2. It is not unique for a given system. Which of the above statements is/are correct? Correct Answer 2 only

Signal Flow Graph:

  • It is a graphical representation of the relationship between the variables of a set of a linear algebraic equation. (Statement 1 is incorrect)
  • It doesn’t require any reduction technique.
  • One system can have different signal flow graph according to the order in which the equations are used to define the variable written as the left-hand side. So, it is not unique for a given system. (Statement 2 is correct)
