Function Perform a linear translation on a single input value from one scale to another. As an
input varies between two input bounds (IB1 and IB2), vary an output between two
output bounds (OB1 and OB2).
Inputs OB2 = output bound 2
IB2 = input bound 2
Inp = Input
IB1 = input bound 1
OB1 = output bound 1
Outputs Out = output
As the input, Inp, varies between input bound 1 (IB1) and input bound 2 (IB2), the
output, Out,varies between output bound 1 (OB1) and output bound 2 (OB2)
respectively. A parameter in the internal parameters dialog box (Index 1) allows the
selection of either a bounded or unbounded output.
When the input value is the same as IB1, the output value is the same as the value
of OB1. When the input value is the same as IB2, the output value is the same as
the value of OB2. The input and output bound values can be either inputs or
parameters. These bound values can be positive or negative, and there is no
requirement that any bound be greater than or less than any other bound.
The following diagram compares bounded and unbounded Ratio outputs.
