 \subsubsection{Key Concepts}
 
 glscopeclient and libscopehal are based on a ``filter graph" architecture internally. The filter graph is a directed
-acyclic graph with a set of source nodes (waveforms captured from hardware or loaded from a file) and sink nodes
-(waveform views) connected by edges representing data flow.

+nodes (waveform views, protocol analyzer views, and statistics) connected by edges representing data flow.
 
-A protocol decode is simply an intermediate node in the graph, which takes input from one or more waveform nodes and
-outputs a waveform which may be displayed in a waveform view, used as input to other protocol decodes, or both. A
-waveform is a series of data points which may represent voltages, digital samples, or arbitrarily complex protocol data
-structures.

+As a result, there is no internal distinction between math functions, measurements, and protocol decodes, and it is
+possible to chain them arbitrarily. Consider the following example:
 
 \begin{itemize}
 \item Two analog waveforms representing serial data and clock are acquired
 \item Each analog waveform is thresholded, producing a digital waveform
 \item The two digital waveforms are decoded as $I^2C$, producing a series of packets
 \item The $I^2C$ packets are decoded as writes to a serial DAC, producing an analog waveform
 \item A moving average filter is applied to the analog waveform
+\item A measurement filter finds the instantaneous frequency of each cycle of the DAC output
 \end{itemize}

+Each filter takes one or more inputs (vector inputs), zero or more parameters (scalar inputs), and outputs a
 signal (vector output).
 
 If the output signal is a complex-valued type (as opposed to a single scalar, e.g. voltage, at each sample) the
 ``Output Signal" section will include a table describing how various types of output data are displayed. Printf-style
 format codes maybe used for clarity. For example, ``\%02x" means data is formatted as hexadecimal bytes with leading
 zeroes.
 
-All protocol decodes with complex output use a standardized set of colors to display various types of data fields in a
