OR
Description of function
The output of an OR is 1 if at least one input is 1 (closed).
A block input that is not used (x) is assigned: x = 0.

NOR
Description of function
The output of a NOR (NOT OR) is only 1 if all inputs are
0, i.e. when they are open. When one of the inputs is
switched on (logical 1 state), the output is switched off.
A block input that is not used (x) is assigned: x = 0.

XOR
Description of function
The XOR (exclusive OR) output is 1 if the signal status of
the inputs is different.
A block input that is not used (x) is assigned: x = 0.
