\section{Introduction}
Unlike DC signals, AC signals are time-varying, posing unique
challenges to recording, characterizing and otherwise studying them.

In this lab, we will examine the circuit depicted in fig.~\ref{fig:circ}, and
focus on comparing the measurement of one aspect of an AC signal --
the RMS voltage -- as seen by two tools: the Digital Multimeter (DMM),
and the oscillscope. We will use numerical and analytical methods to
model this circuit and derive expected RMS values for comparison.

\section{Analytic Modeling Results}
Figure~\ref{fig:circ} depicts the circuit we are studying.
