k Logical Operators (AND, OR, NOT, XOR)
[OPTN] - [LOGIC]
The logical operator menu provides a selection of logical operators.
• { And } / { Or } / { Not } / { Xor } ... {logical AND}/{logical OR}/{logical NOT}/{logical XOR}
• Be sure to specify Comp for Mode in the Setup screen.
Example What is the logical AND of A and B when A = 3 and B = 2?
A AND B = 1

u About Logical Operations
• A logical operation always produces either 0 or 1 as its result.
• The following table shows all of possible results that can be produced by AND, OR and XOR
operations.
Value or Expression A Value or Expression B A AND B A OR B A XOR B
A
≠ 0
B
≠ 0
1 1 0
A
≠ 0
B = 0 0 1 1
A = 0 B
≠ 0
0 1 1
A = 0 B = 0 0 0 0
• The following table shows the results produced by the NOT operation.
Value or Expression A NOT A
