Transposed Signal Flow Graphs in DSP Analysis
Using Signal Flow Graph SFG, the transposition or transposed form of SFG is explained with the help of solved example of second order difference equation. Transposed SFGs are also applicable on fir besides iir systems.
Transposed SFGs, or Transposed Signal Flow Graphs, are a type of graphical representation used in digital signal processing to model the behavior of linear systems. They are similar to regular signal flow graphs, but the direction of the arrows is reversed. This allows for the analysis of systems in the frequency domain, which can be useful for studying the behavior of filters and other systems that manipulate signals in the frequency domain. The Transposed SFG can be used for solving the algebraic equation for the frequency response of the system.

      My 2 cents on the point: Lecture videos are open loop, whereas class environment is a closed-loop system. Real time lectures deals more with the level of feedback, can be more flexible, and inviting students to answer key questions rather than instructor walking through stuff from "a to z". Also, real time lectures are aimed more at developing analytical thinking skills of students, rather than telling students that how well an instructor solves a problem.
