In uni we used quartus

is there any other way? I don't really want to download that large of a program for this, we'd only be on logic circuits for the next few days

I'd highly recommend JFLAP.
The software website looks like it's straight out of the 90s but the program itself is fantastic.
If it asks you to fill out a form, just leave everything blank and hit submit and it'll work without you having to give it any information.

I'm going to use this thread to ask since it's related:

How is this: X1 ^ ( X2 v X3) a boolean expression and this: ((X1 ^ X2) v X'3) not a boolean expression?

How do you draw the first question? For some reason it's more confusing to me than questions with 3 inputs

doing your homework...

>>7688686
if you mean ((X1 ^ X2) v X3'), then they are both boolian expressions

Then my book is wrong?

What you use is partly a matter of taste. CircuitLab is pretty awesome, but it's not free. You can get a demo though.

Best bet for simple purposes: http://sourceforge.net/projects/qlogic/

Best bet if you want to get more complicated:
http://sourceforge.net/projects/circuit/
Logisim is pretty easy to use, and has lots of good features.

Other stuff....
http://sourceforge.net/projects/gatesim/ looks a bit fancier. I don't like the curvy lines.

I've been meaning to try KTechLab. It seems to be microcontroller based, but looks like it has logic as well.

Thank you.

How does this one look

~A ∧ ~B ∨ C

am I retarded ?

>>7688850
Nice, I will try each of them out, thank you

I've used LT Spice (it's pretty lightweight and free)

Falstad circuit simulator. In browser, no DL required and user friendly

the question should probably have parenthesis somewhere. If they were around the not a and not b the you would use the and output to be a input for the or gate
