Second-order RC Circuit Analysis
The second-order RC circuit shown in figure 1 below represents all voltages and impedances as functions of the complex
variable, s. Note, of course, that the impedances associated with Rs, R₁, and R2 are constant independent of frequency, so the 's'
notation is omitted. Again, one of the advantages of s-domain analysis is that we can apply all of the circuit analysis techniques
learned for AC and DC circuits.
To generate the s-domain expression for the output voltage, Vout(s) = Vc2(s), for the circuit shown in figure 1, we can apply
voltage division in the s-domain as shown in equation 1 below. Equation 1 will be used in the prelab computations to find an
expression for the output voltage, vc2(t), in the time domain. Note also that when we collect frequency response data for the
circuit it will be operating at AC steady-state conditions for each frequency tested. Note that under AC steady-state conditions,
s=o+jw=jw=j2πf.
