A logic probe is placed on the output of a gate and the display indicator is dim. A logic pulser is used on each of the input terminals, but the output indication does not change. What is wrong?
Options
A : The dim indication on the logic probe indicates that the supply voltage is probably low.
B : The output of the gate appears to be open.
C : The LOW indication is the result of a bad ground connection on the logic probe.
D : The gate is a tri-state device.
