Unformatted text preview: It is good for the students to see alternate approaches and how a block diagram can be rearranged to achieve the same end. You can ask the students to draw the block diagram of approach (b). Another similar problem asks students to determine if the second simpler circuit really does everything that the more complex circuit does. This requires students to analyze both circuits and make a decision. Although this is a very easy problem, it does point out that complex circuits can often be significantly simplified and still perform the same task. Both circuits produce 1 O 1 11 v v .-= . v 1 v 2 v O 6 18 3 V (a) v O V 1 180 k Ω-3 V 10 k Ω 10 k Ω 10 k Ω v 2 180 k Ω 30 k Ω (b) v O V 1 180 k Ω 3 V 60 k Ω 10 k Ω 10 k Ω v 2 180 k Ω 60 k Ω O 1 k Ω v 1 v 10 k Ω 10 k Ω 1 k Ω 10 k Ω 9 k Ω 1 v 100 k Ω O v (a) (b)...
