Math Transforms

Math transforms perform mathematical operations on signals.

Transform

Action

Absolute Value

Outputs the absolute value of the input.

Outputs the sum of all input signals.

To subtract, use the Port Properties to change a port type to Subtract. The input value of that port is multiplied by -1, then added to the other port values, effectively performing a subtraction. Constant

Outputs a constant value specified in its properties.

Divide

Outputs numerator divided by denominator.

Inverse Scale & Offset

Output = (Input - Offset) / Scale

This is the inverse of the Scale & Offset transform.  Scale and Offset values are specified in its properties.

Invert

Performs a logical inversion. Input of 0 produces an output of 1.  Input of 1 produces an output of 0.

Min/Max

Min = the smallest of the input signals.  Max = the greatest of the input signals.

Multiply/Divide

Out = the product of the input signals. To divide, use the Transform->Edit Ports command or the Port Properties to change the port type to Divide.

Scale & Offset

Output = (Input x Scale) + Offset

Scale and Offset values are specified in the Transform's properties.
