1. The problem statement, all variables and given/known data I have got transfer functions W(s) and Wk(s), where Wk(s) is correction transfer function. So I calculate W(s) and Wk(s) in series. Magnitude graph before correction: Magnitude graph after correction: The task is to make whole circuit and simulate it. 2. Relevant equations 3. The attempt at a solution First of all, I tried to make it by parts: What about 70/s? And am I on the right way with otherones?
