In this experiment s-domain circuit analysis, transfer function of a passive filter and an oscillator circuit
will be investigated. All the theory needed for the analysis can be found in the lecture notes.
Preliminary Work
1. Analyze the circuit given in Figure 1 in s-domain. Assume that it is in zero-state.
Then, find s-domain expression of Vo when Vi is given as Vi = (t).
