Prelude to Computer Science - 7: Logic Gates

[garetfrog]

I bought a textbook called Python Programming; an introduction to computer science and your video's are helping me understand it at a simpler level. Everything is so overcomplicated at the college level.

[TheFallibleFiend]

@garetfrog Many of these lectures are versions of what I taught in college. I asked myself, "What do I wish my own teachers had done to explain things more clearly."

Question, in diagrams, can you have more then one input to a AND, NAND, OR, or XOR gate? How does the XOR handle more then one input? Does it only return true if 1 input is true? Or does it return true when all but one input is true?

[TheFallibleFiend]

@Shadowmil2 You can have multiple inputs to any of those circuits at least in diagram. I don' t think that multiple input logic gates can be bought, but you could make them out of other circuits (either logic circuits or the op amps). I think it should return high if exactly one of the circuits is on, but low otherwise.

@TheFallibleFiend Thanks, that has always bugged me...

u rock dude

[ntshanga]

thanq u hope il make it in ma exams u helped me

[cnitdone]

Nicely done, my prof. is tired of teaching this stuff so moves through it quickly and in a very half hearted way. Makes his explinations hard to follow.

[TheFallibleFiend]

thanks for the feedback. good luck in your class.

[michaelanoelle]

thank you. this makes sense. my professor doesn't, apparently.

[youngthug21]

man this thing is like so difficult and i so need to get a grade 1 or 2......thanks for the simple explanations dude...you really are a lifesaver

[TheLomboo]

yeah, I can it ,its make fun!

[UserIsAnFBIAgent]

Thanx for teaching how different logic gates work.

[liliane2011]

youuurrr theeeeeeeeeeeee besttttt thx to you im did great in my miterm :)

thank you verry muchh i really appreciate your help

[Zoidberg19790]

Well done, I never really understood logic gates before your video.

Will excellent videos like this is there a need to attend uni???

[soulsaber2040]

first year uni here, one of my units is computer systems...my lecturer just made no sense...just another thnx falliblefiend for ur help coz now i think i can pass my test this tuesday....meanz alot, keep up the good work :)

[Raj53212]

Great Work I wish I had a teacher like you. it was very hard to understand my teacher. Thanks

[mjd550]

Thanks again, it is so much more interesting learning this way than going through my univeristy lecture notes !

[IrishMan752]

you guys are learning this before collage!!.Thanks for this it helped me with computer arc.i will tell all the lads about these thanks.

[Oxyarrow01]

In high school, XOR and OR always confused me. It could have also been my teacher. But hey, I get it now :D

Thanks!

[TheFallibleFiend]

You're very welcome. Good luck.

I changed my major in college from computer science to anthropology - partly becuase the instructors were not half as good as you are at explaining this stuff - I think its awesome you are taking the time out to do these lessons! Thanx!

[TheFallibleFiend]

Wow. That's very nice of you to say!

tx,
