slides/graphics-hardware: there is not necessarily an ADC in legacy analog interfaces
A CRT monitor that takes some analog interface as input (e.g. VGA)
most likely does not have an ADC, it directly uses the analog signal.

\begin{itemize}
\item Legacy display interfaces are usually \textbf{analog}:
\begin{itemize}
- \item Transmission through a DAC-ADC encoder-decoder chain
+ \item Transmission through a DAC-based chain
\item Lack of precision, noise and chain error: not pixel-perfect, capped
\item Requires few signal pins (1 per color channel and sync or less)
\end{itemize}
