Function "4: bOut = f (Truth table)"
When the function "4: bOut = f (truth table)" is selected in
, the output value bOut depends
on the truth table parameterised in
.
The following table shows which setting may be required in
to realise the logic
operations NAND, NOR, XOR and XNOR:
Truth table for function "4: bOut = f
(truth table)"
• Each of the eight possible input
combinations can be assigned to
the output value FALSE or TRUE.
• For an application example see
the following section.
