Hey,
I'm doing a digital circuits assignment right now and part of a circuit they give us has something like this:
Where |>o is a NOT gate. (Sorry about the diagram I can't find a good Linux schematic editor.) Now what I need to do is figure out what G's output will be. Now when A and B are both LOW I think that G should be HIGH. The problem occurs when A or B goes HIGH or both of them are HIGH.
My guess is that when A goes HIGH zero volts are produced on the output of the NOT gate. So the Vcc must then drop across the Resistor. However, what happens to the HIGH being produced by the B not gate?
So far I have for a truth table:
A B G
-----------
0 0 1
0 1 ??
1 0 ??
1 1 0
Basically does the NOT gate act as a sink for all of the potential (this sounds weird) when either gate produces a LOW?
Thanks
