The functions of the function blocks in the “Logic library” are similar to the functions in electronic logic gates from digital electronics.
Here you can find blocks, with which you can program logic functions of the Boolean algebra. Besides the Boolean basic functions AND, OR and NOT, further blocks are included.
There are many documents on the internet about programming digital circuits. Sometimes different terminology is used for that matter. You can find useful information, when searching for, f. e.:
- Logic functions
- Logic gate
- Boolean algebra
History behind logic functions
In his paper The Mathematical Analysis of Logic, George Boole made the first logic calculus and proved the modern mathematic logic, which, unlike the general philosophic logic, stands out because of its consequent formalization. (translated from Wikipedia DE: George Boole)
