I have found sketch of something like this in my notebook. It says only XOR. My question is if this is any valid logic gate? And can you explain me this emitter connected to base thing?
The hardest parst for me was the last thing you explained to me. But now it seems logical. Because i know the voltage drop can be calculated using the Ohms Law V=I*R and since I=0 then voltage drop is 0 so Out is still 5 v.
Thank you for your answer, it really helps. But now i have just one more question.
This is from your reply
"...the diodes do not conduct so no current flows through the resistor, no voltage is dropped across it so the output is high..."
I dont understand this part, if nothing flows through the...
Re: Different ways of presenting a circuit
"Didn't your teacher teach you?" well i would not ask this question on a forum if he did.
And also, i dont understand what it mean to connect something to A. To my understanding you need 2 points, so that current can flow from one to the other, thats...
Hi, my problem is that i understand circuits like that:
I can see where where the starting + and - of the battery would be, also i can see where the output is. It is really simple. But then, in school they showed me this
And they tell me that this works like AND gate. I dont understand how V...
