\section{Introduction}

The procedure can be found in section~\ref{sec:proc}. Measurements can
be found in section~\ref{sec:meas} and theory can be found in
section~\ref{sec:thy}.

The procedure can be found in \autoref{sec:proc}. Measurements can be
found in \autoref{sec:meas} and theory can be found in
\autoref{sec:thy}.

\section{Procedure}
\label{sec:proc}

A picture of the circuit can be found in \autoref{fig:picture}.

\begin{centergroup}
        \fbox{A cool graphic would be here. Instead, you get a framed
        box.}
        \captionof{figure}{Some figure.}
        \label{fig:picture}
\end{centergroup}

\section{Measurements}
\label{sec:meas}

Measurements can be found in \autoref{tab:data}.

\begin{centergroup}
        \begin{tabular}{ccc}
                Frequency & Gain & Phase Shift \\
                \hline
                10 Hz & 5 & 0.01 radians\\
                20 Hz & 5 & 0.1 radians\\
                1000 Hz & 2 & 1.5 radians
        \end{tabular}
        \captionof{table}{Some data.}
        \label{tab:data}
\end{centergroup}

\section{Theory}
\label{sec:thy}

The average power over period $T$
%
\begin{equation*}
        A_v =
        \frac{1}{T}
        \int_0^T
        v(t)^2
        dt,
\end{equation*}
%
and so
%
\begin{equation}
        P_v = 4.
        \label{eq:average_power}
\end{equation}
%
By \autoref{eq:average_power}, $P_v < 10$.

We can do Greek letters too, like $\alpha$, $\beta$, $\gamma$, $\delta$,
$\varepsilon$, and others. For example,
%
\begin{equation*}
        \pi \approx 3.141592653589793\cdots.
\end{equation*}
