This made me sleep
Which animation soft is used in the videos of this channel?
Ah, the classic latch RS.
his face looks like a oblivion character
i love the smell of burning electronics in the morning
great
You should do a video on ternary cumputers such as Setun
I’m out. 11:40
This was by far the worst Coputerphile video i have watched. Horrible explanation at the end.
No current limiting? Shame on you sir……
What is that white thing where he using the pins? Thanks 😅
If you are interested in this stuff, go watch Ben Eater’s breadboard computer series
Lots of types of memory, there is bubble memory and core memory now there is digital memory.
Please, could you say the name of that book? Thanks
Memory is a rs nor latch, at least that’s how it’s called between redstoners… Anyone here?
what book was that on 3:00?
Woow..you make it very simple thnx but you were using a boock what his title please…..
THANK you THANK you THANk you!
beautiful video
I really wanted to know what is the working of the sr latch
thanks
once again great video…
There is an intuitive way to explain what’s going on:
Consider two NOT gates, labeled A and B, feeding into each other. This simple circuit already stores memory. When A’s input is 0, its output is 1. Then if you connect A’s output to B’s input, B’s output becomes 0. Connecting B’s output to A’s input does nothing, because A’s input was already 0.
This is a stable circuit. The wire from A to B is on, but the wire from B to A is off. Now what happens when you supply power directly to the wire from B to A? A’s input becomes 1, and its output becomes 0, so B’s output becomes 1. By doing that, you have "flipped" which side of the circuit is "powered".
This is effectively identical to the RS NOR latch of this video, the only difference is that the video uses NOR gates instead of NOT gates, which allows you to use the second input of the NOR gates to supply power to one side of the circuit.
(This can be easily demonstrated in minecraft with two redstone torches feeding into each other)
How did i get here
How come every single computer guy looks like this? lol
It’s called a latch
7:10 diagram in s really nice!
Wtf i am doing here
I was looking for kim kardasian brains
I hope that your next videos are more direct to the point..its so time wasting
But can it run crisis?
Assumes you have an understanding
Rs nor latch
Great video, seems strange that the term "flip flop" wasn’t mentioned anywhere? Also these can be built with NAND gates instead of NOR gates but then they become active low rather than active high (so you need a 0 input to set the output to 1 and a 0 input to reset it).
I’ve seen this arrangement using pneumatic valve blocks the pull down resister function was an a air bleed instead.
Ok @computerphile. I cannot find the answer to my query…maybe you could help? I got your vid by asking "how can you put information in a computer chip?". I understand the whole 1 on, 0 off deal, that’s not my question though. How in the world does those chips, made out of metal and stuff you could tell me I hope, hold numbers? How does a machine become capable of being able to put binary code into it in the first place? How did they figure that out too? What is so special about those chip, silicone right, that makes them able to put a language created by man, I hope or who if not, to have the ability to turn inputs off or on? I find it rather difficult to ask the correct question here. Lol. For I wanna know how it all began. How did they find out how to make the chips, how did they figure out that they could also turn those chips on or off? You getting where I coming from here? I hope so. If not I can put more detail I suppose. Just lemme know
Great!!
I severely dislike that explanation.
While logically, a NAND gate is taking an AND gate and then putting a NOT gate on the output, electrically it typically isn’t. Electrically it is very easy to make a NAND gate directly, and for CMOS, PMOS or NMOS, NAND gates are made directly and an AND gate is actually a NOT gate fed by a NAND gate; likewise the NOR gate is done directly and an OR gate is a NOT gate fed by a NOR gate.
They should have mentioned the S-R flip-flop’s inherent flaw, which is: if both R and S are 1, on the output Q and /Q will be equal to each other, which is obviously not how boolean algebra should work.
Of course there is an easy way around this, just don’t let R and S be equal to 1 simultaneously. And the J-K flip-flop fixes this issue, but that requires a clock signal to work.
Just thought this should be mentioned when talking about S-R filp-flops..
what is the name of that book he was reading with the different logic gates on those chips?
Those connections on breadboard hertz
the office: electronics
Why didn’t he show what happens when both inputs are 1? That’s the only non trivial part.
KitKat a lot of fun ! #Epitech
I just figure out why minecraft players call this an ‘rs nor latch’ I had no idea the name was based on actual terminology
He looks kinda like Larry Page!!!
Is all human are fool
As a software type, I wouldn’t understand a thing from the video if I did not know Boolean algebra
What is that book. I always have to Google the the data sheet.
Wish they put this kinds of videos into Television instead of regular empty content show they put on TV’s nowadays which teaches you nothing. I understand it’s entertainment business but everyone has their own definition of entertainment and I was entertained by this.
Q and not Q are mixed up but…..
What
Practical Electronics Handbook
2nd Edition THAT HE USE
Name of the "Gate’s almanac" book?
