    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}
