Let us simplify (reduce) this block diagram using the block diagram reduction rules. Step 1 − Use Rule 1 for blocks G 1 and G 2. Use Rule 2 for blocks G 3 and G 4. The modified block diagram is shown in the following figure. Step 2 − Use Rule 3 for blocks G 1 G 2 and H 1. Use Rule 4 for shifting take-off point after the block G 5.
