- Homework Statement:
- Determine the transfer function of the block diagram

- Relevant Equations:
- Equations for Block Diagram Algebra

Step 1: I first started by reducing the inside of the block diagram of picture "bd" (the portion with G

I obtained

I'll call this term "

Step 2: Then I'm left with two terms feeding into a summing point:

I'll call this term "

I can reduce this diagram as I did in the first step:

The solution, on the other hand, is

"bd2"

I am not sure if this is a mistake (to add G

Any help is appreciated, apologies if I've left anything out or made my solution unclear in anyway.

I am not sure if this is a mistake (to add G

_{3}instead of subtracting it) or if I'm not seeing something.Any help is appreciated, apologies if I've left anything out or made my solution unclear in anyway.
