First-order High-pass RC Filter Analysis
The first-order high-pass RC filter shown in figure 3 below represents all voltages and currents in the time domain. We will again
convert the circuit to its s-domain equivalent as shown in figure 4 and apply Laplace transform techniques.

Again, to generate the s-domain expression for the output voltage, You (S) = V2 (s), for the circuit shown in figure 4 above, we can
apply voltage division in the s-domain as shown in equation 2 below. Equation 2 will be used in the prelab computations to find
an expression for the output voltage, xc(t), in the time domain.
