Description
The Boolean functions AND (logical AND), OR (logical OR), NOT (logical NOT, negation) and XOR (logical exclusive OR) can be used to connect binary expressions, such as digital signals. According to the rules of Boolean logic, the functions return the value TRUE or FALSE as their result. Digital signals, calculated (binary) expressions or the numerical values 0 or 1 can be entered as parameters.
The result can be presented and evaluated as a new expression, such as a signal. So, binary signals can easily be generated and can then be used as conditions for other features.
