s.t like D-Type Flip-Flop

I doubt maybe it has some how, kind of "logical memory" :&

Dear hosseinsanaye! Your circuit "Digital Logic Homeworks" can easily be adjusted to two divider type D Publishing modified circuit entitled "Digital Logic divider two type D" to Viewed.

I don't know what this is meant to do! However, if we call inputs A & B (top and bottom respectively) and outputs C & D (top & bottom respectively). With 2 inputs there are only 4 possible states thus: A=0 & B=0, A=0 & B=1, A=1 & B=0, A=1 & B=1. We can simulate these input conditions in 2 steps and note the output conditions. First, remove the 2 logic sources at the left hand side of circuit. Connect inputs A & B together. Add in a Logic Train and connect it to the inputs. In this way the conditions A=B=1 and A=B=0 are created. Run simulation and you'll see that, for both these conditions, output C is low (0V) and output D is high (5V). Now, pause simulation. Put a NOT gate in line with the Logic Train going to A input only (or B input only, it makes no difference which). In this condition A will always be opposite to B so we are simulating the A=0 & B=1 and the A=1 & B=0 conditions. Start simulation and note that for either condition output C is high (5V) and D is low (0V). Expressed in Boolean algebra, C=NOT A & B or A & NOT B. Also, D=NOT A & NOT B or A & B. If you were to draw out the truth tables you'd see that output C is an EX OR and output D is EX NOR. What the intended function of the circuit is, I have no idea! Note also that C is always opposite to D output. You could make the circuit with a just a single EX OR and EX NOR gate but often you use gates that are available (ie spare) in ICs you are using in other parts of your circuit. In this way you don't have to add additional chips to your PCB even though the circuit looks more complicated. Someone brighter than me may have other suggestions for the use of this circuit.

Thanks budd, awesome analysis! I think my TA doesn't know the purpose him self :}

And Another question :) Can I merge multiple published circuits in EC?

@pedro Thanks for the hint !And the circuit you published. I bookmarked it ;)

Hi hosseinsanaye. You are welcome! You can use that same method for any digital circuits although more inputs makes it a longer process. I'm actually quite new to Everycircuit and have just been searching for 'Help' pages or documentation and, if they there, they're not easy to find. Guess you are wanting to 'cut & paste' to save having to draw the circuit yourself. Would be a useful feature - can anyone else help with this please? P.S. Out of interest, where are you in the world? I'm in the UK.

i meant copy & paste.

Not so far from you 😝

Actually my ip says that I am from UK too 😀

Your IP? Don't you know where you are lol?

Only asking as your 'thanks budd' and 'awesome analysis' made me think it was USA.

.... And what's your TA please?

Asked Everycircuit about merging circuits. Their reply :- Right now we do not allow import of one circuit into another. What you can do is save a copy of the circuit as another circuit and then add your components to that. Not sure if that does the job for you but that is the best EveryCircuit can.

Thanks for searching and asking the admin for it 😉 Merging multiple circuits might be an incredible feature comming up for EC, and I hope to see it at later updates😍

And about where I live; I live in Iran but I speak English as Americans do 😉 Finally my TA is not an object 😝 It stands for "Teaching Asistant". He is a graduate student of my professor,wich help students on their journey through this electronics course by giving 'em homeworks to be done, and here is the stating point of my story to use EC as a cheating accompaniment 😜

Iran. That's nice! You notice how I try to explain how/why a circuit works rather than just give an answer. This way you understand rather than just copy. So I don't see you are cheating :-) All the best, Robert.
