Maybe something like a "data flow" diagram would help.

For instance, if your processing looks like this

g[t_]:=f[t]-f[t-1];

then it is usually represented diagrammatically as (evaluate the code below 
to generate the diagram):

<< "Graphics`Arrow`"

$TextStyle = {FontSize -> 16, FontWeight -> "Bold"};

{a, b} = {1/10, 1/5};
Show[Graphics[{Arrow[{0, 0}, {1, 0}],
     Arrow[{0, 1}, {1/2 - a, 1}], Circle[{1/2, 1}, a],
     Text["\!\(z\^\(-1\)\)", {1/2, 1}],
     Arrow[{1/2 + a, 1}, {1, 1}], Arrow[{1, 1},
      {3/2 - b/Sqrt[2], 1/2 + b/Sqrt[2]}],
     Arrow[{1, 0}, {3/2 - b/Sqrt[2],
       1/2 - b/Sqrt[2]}], Circle[{3/2, 1/2}, b],
     Text["-", {3/2, 1/2}], Arrow[{3/2 + b, 1/2},
      {2, 1/2}]}], AspectRatio -> 1/2];
