WEEK 03: BLOCK DIAGRAMS

Sections: Configuration | Summer | Take-off Point | Element/Block | Solutions | Student's Tasks

Element Manipulation/Resolution

1. Cascade (Series)

b = aG₁G₂

2. Tandem (Parallel)

b = a(G₁ + G₂)

3. Interchange

b = a(G₁ G₂) = a(G₂ G₁)

3. Feedback Path

d = aG / (1 + GH)

3a. Inserting a Feedback Path

d = aG

3b. Removing an Element in the Feedback Path

d = aG/(1 + GH)

3c. Inserting an Element in the Feedback Path

d = aG₁/(1 + G₁)

4a. Removing an Element in the Forward Path

d = a(G₁ - G₂)

4b. Inserting an Element in the Forward Path

d = aG₁ - a

5a. Removing an Element in the Forward Path

d = a(G₁ - G₂)

5b. Inserting an Element in the Forward Path

d = aG₁ - a
