Digital Logic - Decoders

This is one of a series of videos where I cover concepts relating to digital electronics. In this video I talk about decoders, how they are made, and how you can use them

[@Shockszzbyyous]

i never imagined that some of these logic circuits could be so simply interpreted, and yet could create such complex manchines as the computer i am currently on. I realize now that you could do some microcoding this way with decoders ! really nice :)

"both need to be high" and this video was posted on 420. jack confirmed stoner

[@linhdo1738]

Besides the helpful information, reversed writing at its finest!!!!! WOW! Wait, or is there any photography trick here? Like using mirrors? I don't know, whatever that is, I just find it awesome! lol

[@DaveTassoni]

+Carlynda Do They flip the video around so that the viewer can read it

[@linhdo1738]

Thank you. Still cool right lol

[@TheCarventer]

+David “Dave” Tassoni : No, he flipped the video, but in order to do that, he had to write reversely! That is why you can see him behind the letters, not in front of them. This guy has an incredible talent

[@warguy5591]

No he doesn't have to write reversely? He is standing behind a glass and writing normally, then the video is flipped around sideways... That's why he appears left-handed

[@aienpotter82]

google 'The Learning Glass' by Matt Anderson. this guy uses the same mechanism to that. and nope, he wasn't writing reversely.

[@yiithtp]

I can't explain how much this is helpful.textbooks make it complicated . thank you

[@TheSourLemonz]

looks like you're drawing on my screen

[@FuzzlordEffects]

Thank you so much! Great series of videos.

[@JesusPbravo]

Thanks for making this video, it helped me a lot.

[@WoodyWoodstaOG]

Does this guy write mirrored??

[@joshbarber89]

Anytime I have a question, you always seem to answer it. Thanks

[@rook37]

thanks for the midterm help 2013 jack buffington

[@lorenzvo5284]

So an encoder works the other way around, but without and-gates?

[@krishnakk7589]

may I know how the truth table for this decoders was written..

[@BilalBinAmeer1]

In the very end when you combined two 2x4 decoders to make a 3x8 decoder you used C as enabler. But there must be MSB connected to enable pin which is A in your case. Overall video lecture was great.

[@auyerrafael3944]

Do you write backwards or flip the video in editing?

[@yelectric1893]

Thank you. I dont have enough pins on my microcontroller, so I will get some more functionality with this. Thanks!

[@MrSocialish]

This guy looks like Mike Dirnt from Green Day

[@itz_Raed]

LOL I was saying the same thing!

[@ThisIsMMI]

How are you writing everything in reverse? Doesn't it become confusing for you?

[@nishantmor5167]

how are you writing this... or is it edited

[@carlmax6112]

He is writing on a glass

[@Shockszzbyyous]

couldn't it be that he is writing on a mirror? and then just has the cam next to him, wait we would see the cam ?

[@muhmho1587]

It's logic man

[@bawad96]

You the man

[@kthomas8231]

What is an enable?

[@parmeet44]

Enable is used to enable/disable the circuit, 1 represents Enable and 0 does Disable

[@livb4139]

do you have to write backwards when drawing on that crystal thingy?

[@lj_fin827]

anyone else watching this to make a redstone computer in minecraft

[@livb4139]

is there any reason I should use this rather than just a demultiplexer?

[@zangetsu_h]

This outro is perfect sir! Hahah I really like it.

[@nadred5396]

why did you draw it so that 01 outputs 2 and 10 outputs 1?

[@inserthearthere4788]

That sound kills me

[@Shazzyb0y14]

that was very informational! Thanks for the upload! :)

[@O2Obaid]

helped a lot thanks

[@vineethcmps]

Really good.....

[@ericsumma7654]

Sorry I'm a bit late to this discussion, just a small addition to your final '3 to 8' decoder. If you had used a separate '2 to 4' decoder to generate 4 separate enables (first level), to four decoders (second level), you would have gotten a '4 to 16' decoder overall. The tradeoffs are time delay, additional current demand and space on your circuit board. Otherwise an enjoyable video, including for review.

[@80amnesia]

nice examples

[@lafeo0077]

man his subtle smiles make me worried that he might mess up! (FOR THOSE WHO ARE NEW, HE DOESNT MESS UP)

[@reilandeubank]

This video teaches decoders in an incredibly simple way and his facial hair is simply immaculate. I wish I could hit like more than once

[@eizazghzali7196]

helpful information but in decoder with 3 input why you using OR gate. why don't you using and gate?

[@masoodtariq7839]

i watch many youtube videos but no one explain me how decoder works.... thank you for explaining this topic.......

[@eduardodelacruz1166]

great explanation

[@ioannaathineos5269]

Captivating

[@mpik97]

I love you.

[@AbdulrahmanSaeedMAli]

LOL! so marry him!

[@saadawan8283]

Thanks.

[@ellegaardtheengineer9050]

Hi I'm 11, in my school they don't teach me electrónics, I come hére because I was building happily my 2-BIT ALU in Minecraft when someone said, you'll need a decoder. I came hére and I didn't understand es Nothing, i dont know What type of Logic gates are the ones that look like AND but have a circle in front. I know the instructions are 8 BIT, but what is a diode, and how do you know that the wires you choose for decoding: 0,1,2,3 were right. Sorry, I'm only 11 and in my school they dont teach me electronics.

[@saeedhassan7441]

+Ellegaard The Engineer , you want some help? come over yahoo [e-mail] maybe i can help you through this ! :) cheers

[@ellegaardtheengineer9050]

Saeed Hassan Thx

[@saeedhassan7441]

My pleasure!

[@MODDINGPRIME]

15 years old bruh

[@human4566vv]

Go away stupid

[@andyle8207]

would this still be the case if im using 2 3 bits inputs?

[@ruyangulieseyie7015]

why is even parity not used for decoder outputs

[@yasharthyadav8562]

This video deserves million +subscribers

[@krishnakk7589]

beautiful series of videos helping me a lot..thank u sir

[@cathalfoley4004]

Come be a lecturer in UL plz

[@cyliat.s3444]

He looks like Colin Firth !

[@amihartz]

Good explanation, m8.

[@kaukiaa4590]

your explanations is crystal clear!!!!

[@jaketracy1375]

Your are the real MVP my good sir

[@darkstatius]

Great video!

[@diquetz]

Awesome video. Helped me a lot!

awesome.

[@DonHYPER007]

Very Very useful.

[@darshantatiya]

[@hirakmondal6174]

*_MIRRORED_*

[@moazelsawaf2000]

Thanks sir ❤

[@farnazzinnah8541]

why the background music is the tone of a hindi movie? xD

[@icap8801]

THANKS FOR YOUR VIDEO JACK.

[@smk9320]

Are you left-handed or right-handed?

[@swalker157]

He’s writing with his right hand. Men’s shirts have buttons on the right side.
