lol ! 5 years ago ! i dont know what happened then , but today i am a in a very secure job and doing well :) Okay today more than the glass , his beard next to the ears is bothering me more LOL LOL @@MrInventer80
One addition: Not only hold time but setup time can also be negative. Setup and hold time are basically max and min skew values relative to the clock edge for edge triggered timing to be successful. Depending on your reference clock edge either can be negative.
so you are inverting the video horizontally right? the other option is your are both left handed AND writing backwards. I think first option is more likely!
asdFRap, I think if your propagation delay is smaller than hold time, the flop won't work properly especially during shifting since there usually has no logic between 2 shifting flops
So is the clock timing the signals???and meaning of faster clock means that more signals will be timed by clock in a lesser time???in others words can we say that more number of signals in a lesser time will make the circuit faster???
What is a "clock event?" A certain input will result in a certain output after a certain period of time, and this period of time is known as the propagation delay, yes? the clock is simply used to count system pulses at a certain frequency in order to determine how much time has passed for a given process/set of processes, yes? I don't see how a clock can even have a rising/falling edge aside from counting pulses at a certain frequency (time) or how these edges could effect the output of a circuit? Would someone be willing to explain this to me? If so, thank you in advance.
o A capacitive level sensor determines if the volume of liquid in the tank is too large. o Excessive pressure is monitored by an optical pressure sensor at the top of the tank. o A temperature sensor mounted mid-tank will ensure the temperature does not get too high. If ANY of these parameters is exceeded, the corresponding sensor generates logic HIGH. The three sensors are monitored by a safety system controller, shown below. It controls the behavior of three active-HIGH indicator lamps. o A green lamp, designated ‘Acceptable’, indicates that the system is functioning normally. Normal is defined as the condition where no more than one sensor indicates an out-of-range condition. o A yellow lamp, called the ‘Alert’ light, illuminates when any TWO sensors indicate an out-of-range condition. o The red lamp is the ‘Danger’ light, and comes on when ALL sensors are out-of-range. In this final condition, ONLY the red lamp is on. Digital Logic Bonus Assignment #16 Your Assignment: On a separate piece of paper, NEATLY design a simplified logic circuit that will satisfy the requirements for the three indicator lights. You may use any type of gate or chip to complete this project. The number of gates is restricted to 15. Do not split your outputs from any one gate. You may use as many inputs as you want, however, your outputs must not be split. Inverter gates or bubbles will not be counted as official gates for this project. The project that uses the fewest gates will receive the highest bonus mark of 5% on their exam component. However, all successful projects will receive a bonus
After the initial he's writing backwards I noticed his shirt is buttoned the opposite way. So its either a woman blouse or the video is flipped. Good video though
I stopped at 1:21 , further watching...cos it's terrible explanation. Even what he says, doesn't match what he draws, let alone what he describes.... He is matching the CLK signal per se, as the reflection at OUTPUT, telling, the time lapsed since the change in input is reflected at the out..blah blah....input is STILL - ZERO, flat line....boooo
For future reference, stop squeaking the damn marker. you do not write on a whiteboard the same way you write on paper with a pen or pencil. other than that good job
Captain Rhodes I actually still don't get what's wrong about that. it is just another way to show you some shit. it is not distracting so it's no contra. And what I personally think is nice is that he doesn't have to turn around all the time which I think is very nice. don't get upset with every shit you see...
I think it would be better if he had used the whiteboard because of the annoying sound generated by the pan and the glass. But it doesn't much matter. It's still a nice video.
Neither. I'm behind glass but write normally. I flipped the video left to right when editing.

Yeah, go to datasheets and see negative hold time. Thank you boss !
2 comments:
1) Long sideburns
2) He's writing backwards
I thought he wrote the "d" in "hold" the wrong way. Turns out I was wrong. I was wrong....

I think he might be writing normal, just flipped the screen
The first shirt I saw having its pocket on the right-hand side. Good video.
i have an interview tomorrow. My head is spinning seeing him write the diagram standing behind the glass !
how did the interview go?
lol ! 5 years ago ! i dont know what happened then , but today i am a in a very secure job and doing well :) Okay today more than the glass , his beard next to the ears is bothering me more LOL LOL @@MrInventer80
its really helpful and nicely explained
Gee, Dr Side-burns, that actually helped! Thank's!

Those sideburns though.
He's not writing backwards, he can write normally and the flip the video vertically.
so you are inverting the video horizontally right? the other option is your are both left handed AND writing backwards. I think first option is more likely!

Nice video...how can we measure clk and data timing diagram with a test equipment any recommendations thanks
Quick observation, let me know if I'm wrong. A negative hold time decreases your setup margin.
Great video but please do something about the horrible noise sound of that marker.
Excellent !
Excelente video ⚡️
great ancient video, still useful lol
Good one, but please use a normal board, would you?. I often got dragged away with that thing.
Great video! Thanks a lot!

Are you in front of a mirror or are you writing backwards on a glass?! Its amazing that I am more focused on that than the lecture!
Good explanation Jack!
Can you elaborate on negative hold time....
hahah lol
Awesome!
that's different.. i like it
Wow thats a new idea. are you fliping sides in the video after recorded? or writing backward?
God bless your soul
Thanks sir..☺️
thanks
With being on Whose Line Is IT Anyway, how do you get time to make videos like these? TIME MANAGEMENT. THAT'S HOW.
bad explanation - after all there is no explanation . its just stating the definition .
what is contamination delay?
+astrocreep51 Same question what is contamination delay??
Kalemin sesi cok tatli
He's writing backwards! How awesome lol.
thats too hard. I guess he's writing normally forward then reverse the video.
Mirror Rotation
I can write too
After the initial he's writing backwards I noticed his shirt is buttoned the opposite way. So its either a woman blouse or the video is flipped. Good video though
why only 50% of propagation delay
Ka manatay tyacha tyalech mahit
*_1.5x is fine for me_*
3x is fine for me ,kiddo
write it on the board
I study computer engineering i want some help from you can you give me your email ?
escutei um kraftwerk no final.
Reminds me of Hugh jackman.
I was helpful, but if you use the regular board , will be more convenient. Thnks

Hi Doctor Who
just use the whiteboard man.
Captain Rhodes what's wrong with that?

But it doesn't much matter. It's still a nice video.
chutia explanation!
