Engineering Asked by 3leggedquid on August 8, 2020
I have been testing basic circuits in SimulIDE. I created a basic exclusive or circuit that works most of the time.
There are two inputs.
When both inputs are off the bottom LED does not light up, that is correct.
When 1 of the 2 inputs are on, the bottom LED lights up, that is correct.
When both inputs are on, the bottom LED still lights up, even though an exclusive or circuit should only output ON when 1 of 2 inputs are on. In other words, if both inputs are on, the bottom LED should not light up.
I was wondering if timings could be the problem, but I’m not comfortable enough with circuits to trouble shoot this. Why does the bottom LED light up when both inputs are ON?
(Bottom LED should be off)
I hope this is the right place to ask, and that the tags are correct. If they are not, please let me know.
