Boolean Logical Operators (Conditions)

Two Inputs Truth Tables

Inputs Output
A B AND OR NAND NOR XOR XNOR
False False False False True True False True
False True False True True False True False
True False False True True False True False
True True True True False False False True

Having separate rows for False/True and True/False is traditional for truth tables, but there is a simpler way to think about and present this since A and B are interchangeable for all Boolean Logical Operators with two inputs available in TC2000.

Inputs AND OR NAND NOR XOR XNOR
False False False True True False True
Mixed False True True False True False
True True True False False False True

One Input Truth Table

Input NOT()
False True
True False
