https://6002x.mitx.mit.edu/discussion/question/26482/what-i-learn-from-lab-2bstart from massAt first, I designed a very complex resistor network. I think with solving resistor's values, maybe there were some broken link or short link. The resistor=infinity means broken link, and resistor=0 means short link. So, basically, I want the answer emerged by math. My first design
If you solve the Lab 2B, you will find my design is not complex enough to cover the all link, and not simple enough to solve the equations.
follow the sampleThen, I followed the sample "Lab 2A: Superposition Experiment". I tried to modify from sample. In the sample, source 2 is a current source. you can not just replace it with a voltage source. Because, when you calculate the contribution of source 1, there will be a short. So transfer a current source into a voltage source is the key to solve the problem. Once I solve the source replacement, I solve the Lab 2B.
learn to separateI am curiosity how other people solve. So I browse the discussion. I found [this](https://6002x.mitx.mit.edu/discussion/question/26116/lab-2b-stuperposition) @BopazTheGreat gave a very interesting design
In his design sinusoid voltage is oscillating correctly, but the magnitude of square wave is too small. To correct the value, it's just math. @BopazTheGreat show me another pathway to separate the circuit into two different parts. I would rather to change his circuit into another form:
With this form, I think I can have a more beautiful solve. I simplify his circuit.From 2 to NWhat if I want to mix more input source? So I extended the problemVoutput= a1 V1+a2 V2 +a3 V3 .... aN VN the circuit @BopazTheGreat can be extended. After simplify.I solve the N input sources in [https://6002x.mitx.mit.edu/discussion/question/26456/from-2-to-n](https://6002x.mitx.mit.edu/discussion/question/26456/from-2-to-n)
