The input to the AFC module is limited to the boundaries given by the stage and active area setup
–
whichever is smallest.
In addition, one can limit the output further, by imposing smaller limits in the parameters “Lowest
X
”, “Highest
X
”, “Lowest
Y
” and “Highest
Y
”.
Rotate and translate:
The different fields are variables in the equations for rotation and translation. Rotation has four variables, and translation
has two. Value X and Y are the outputs from the scale and limit function.
Rotation equations:
𝑥
′
= 𝑎𝑥 + 𝑏𝑦
𝑦
′
= 𝑐𝑥 + 𝑑𝑦
Translate equations:
𝑥
′′
= 𝑥
′
+ 𝑎
𝑦
′′
= 𝑦

Filter parameters
The AFC module also contains a set of filter parameters.
These parameters shall not be changed from their default values unless after consulting TTA.
