I am afraid that this looks more than suspiciously like an exam paper questions. The English is not brilliant and makes it hard to understand some of the questions and this is something that you should be doing for yourself. I will assume you have textbooks to read which explain the theories that these questions are asking you to demonstrate. Is there something about them that you don't understand? It would be a lot more useful and fair if you asked for clarifications on the theories and not for answers to the questions.
And before anybody starts getting "offended" I am filling out my own assignment papers right now and I'm doing it myself!
Sorry my English is not good.
In "Electrical Circuit 1" course, our instructor gave us these questions for additional score.
he say this circuit is from Book "Medical Instrumentation Application and Design (by John G. Webster)". I searched the book but not found.
Unfortunately i'm software engineering student.
I summarize my questions:
1- What does this circuit do?
2- Calculate
H using voltage division rule.
