\subsection{Deskew}

Moves an analog waveform earlier or later in time to compensate for trigger offsets, probe length mismatch, etc.
It is generally preferable to deskew using the skew adjustment on the channel during acquisition; this filter is
provided for correction in postprocessing.

\subsubsection{Output Signal}

This filter outputs an analog waveform with one sample for each sample in the input, phase shifted by the requested
offset.
