Flip-Flop Frequency Division 

The thumbnail for this video says "Divide by 2,4,6,8", where I was curious about "6". There's nothing about it in this video.

... and in the 90's we figure out the signal's oscillation, by just asking R.E.M., "What's the frequency, Kenneth?"

What if I want to divide some higher frequency, let's say, a couple of GHz? Those CMOS chips doesn't seem to be that fast.

Thanks for the video. According to datasheet of CD4013, it can handle up to 24Mhz (input) frequency. Any recommendation about dividing higher frequencies, say 300Mhz? Thanks,.

build a synthesizer!

Great presentation. I'm looking to use such circuits to move speaker cones in ways that some humans find pleasing. Some big nasty octaved sounds that are mic'ed from a distance as well as a fun guitar pedal? For real though, I now know more about flip-flops to the point where I might be able to apply something. ✌

Where we will apply this kind of flip flop in electronics? Sir required frequency we can make easily you know ?

How fast can we go with the original frequency? Can this be used to divide 25MHz to give 12.5MHz? Would this frequency be too high for a breadboard and would the flip flop be able to keep up?

What's the difference between using this method, or using an RC filter, or some sort of filter network? Also, is this the same principle that occurs in a function generator?

Best review of flip-flop frequency division I've seen on the 'Net! Thanks.

Great simple practical circuit. Thank you for putting this video together. Please tell us what’s the input voltage, especially for the crystal.

Been breaking my head on clocks and frequency divisions while debugging an issue with an old 1983 videocard with lots and lots of logic chips. Love your videos ... they are coming in handy ... but still no working videocard :)

Can you tell me kindly how can I convert 1 Ghz frequency to 80 Mhz frequency?

I use a "Flori-duh" flip flop. Sorry, a Friday joke. Have a great weekend Paul.

Thank you my friend... You are always so clear to explain things! This method can be the solution to drive the clock for my old style VDP TMS9918 cause the right crystal is not so easy to find but the double freq one is very common. So thank you very much... a big CIAO from Italy.

"We're at 5 microseconds" would indicate a 10 microsecond period and thus only 100kHz frequency. I think you meant to say that your scope was set at point five microseconds which would support the 1 MHz wave on screen. And I think I saw the selector at .5 when I paused the video. But we all knew what you meant, NBD. Also, I did not notice a grounding strap on either of your wrists. How often do you fry a CMOS chip? :)

Does it needs to be a square wave? Can you feed a sine wave instead to be divided?

how do you divide by 3.5 can't find any info on it Thanks Mate

This is just what i needed for my project! Thank you so much

Thank you, Paul. Good memories of electronics classes throughout high school back in Calgary, AB.

Thks, cursive Fs rule!

Thank you so much❤

Thank you for the video and the schematics. I was looking for a video on how flip-flops are used to divide a frequency signal. I mean, how it actually works. I would love a video about that.

Nice vid. Are there premade voltage devider chips that have many tiny flip flops inside one chip the size you have shown, to reduce a frequency by, for example; 10? It just seems like alot of space to have to use a bunch of the ones you shown to divide a frequency by alot, and im guessing there is one out there but i don't know what its called to find it and learn how to use it. Can you help me with this? Thanks

Hey Paul !! ... What happens if you feed back from the last flipflop to the first in the chain ? Or can you even do that ? 🤔 And what about sine wave division ? 🤨 Happy St. Patrick Day guys 🤗 😎👍☘🍺

Good basic demo of frequency division/ counting with flip flops....would have been nice to show two traces at once - output of the oscillator and flip flop...since I believe you have a 2 channel scope there.

Probably you should mention to those who just started with electronics that division by 2 is made because flip flops work only on the rising edge. That's why it's divided by 2 (and not 3, 4, etc).

I'm a Software Engineer looking to understand low level machinery, a Binary Counter is really important to me because that's how a Program Counter (A.K.A. Instruction Pointer) is based of so I think that wiring both Synchronous and Asynchronous (Ripple Carry) Counters is fundamental to wrap the head around this concept. I'm not very smart so I had problems learning assembly code so that's why I need to see things working at the most basic level. Thank you.

THOSE GOOD ALL DAYS IS WHEN I LEARNED ELECTRONICS FOR A.S. DEGREE IN ELECTRONIC ENGINEERING TECHNOLOGY.THE OSCILLOSCOPE WAS THE THE ONLY WAY GOT OUR FREQUENCY MEASUREMENTS.

Humm... What can I make with that? 🤔

Very good understandable and Clear explanation.Thanx a lot

A very interesting and informative video Paul 👍👍

the T flipflop is the one i use to do the frequency divider

I like all of your videos, thanks

I had a friend who drank Ripple and as he drank it, his mind was divided into smaller sections :). BTW what scope were you using? Looked like old analog. Good job as usual, clear, concise, interesting.

Close enough for guvmint work.
