Basic components
The basic components provide fundamental functions
and in many cases, do not require specifying property
values. These parts are described below.
CONST
The CONST part outputs the voltage specified by the
VALUE property. This part provides no inputs and one
output.
SUM
The SUM part evaluates the voltages of the two input
sources, adds the two inputs together, then outputs the
sum. This part provides two inputs and one output.
MULT
The MULT part evaluates the voltages of the two input
sources, multiplies the two together, then outputs the
product. This part provides two inputs and one output.
GAIN
The GAIN part multiplies the input by the constant
specified by the GAIN property, then outputs the result.
This part provides one input and one output.
DIFF
The DIFF part evaluates the voltage difference between
two inputs, then outputs the result. This part provides two
inputs and one output.
VALUE constant value
GAIN constant gain value
