('Expression1')+ ('Expression2')

Description

All signals and expressions can be processed by fundamental arithmetic operations (addition, subtraction, multiplication and division). If digital signals or expressions are used as operands in fundamental arithmetic operations, the program translates the TRUE value as 1.0 and FALSE as 0.0. The result of a fundamental arithmetic operation is always an analog expression.
