This is absolutely brilliant. I am a very senior citizen trying to learn subjects that I was supposed to learn many years ago. I thought it was Impossible until now. Thank you, thank you, thank you
@@ob1keno227 The more witchcraft-y thing is that it is not witchcraft at all. We understand it very well, through hundreds of years of progress of science, technology, engineering and math. Take some physics classes and it won't be "witchcraft" anymore.
Yea, this is not our tecnology. Aliens are sharing this to us as time gets by. People don't see the impossible jump from one technology to another. Only know to say "ThERe ArE GeNiUsEs".
Don't forget to say that when receiving the waves of FM the device that receives them decodes the waves from a already written library of numbers for each wave. So this is why its so fast, each wave is already programmed to read FM .This is why AM radio is not as good as FM As am does not decode it just reads the waves as a high or low pitch wave. The reason this is so important is people still don't understand how it works as a whole. So each radio depending on who created it, works with a already written program to decode each wave as a one or zero. If you only have a AM radio it does not have any prerecorded information in it so it just picks up the waves and send them to your speaker. We use to call it a echo machine as it would just echo wave sounds into your speaker. But FM will read the waves like zeros and ones depending on the burst of frequency of each wave. If its one short blast or wave, then its a one. if there is a relaxed wave its a zero. The higher the range for the wave, the higher the pitch, the lower the wave or the more relaxed the burst, the lower the pitch.
@@MrBeen992 yes and no, over the years it's advanced to be what it is. Like with WiFi. But yes, you are right. But the wave was recorded and received different.
Yes! The carrier frequency for Wi-Fi is about 2.4 GHz, which is the same frequency as the radiation emitted by most microwaves. This is why microwaves can interfere with Wi-Fi signals. We used a Wacom tablet and the SmoothDraw software to make the video.
All these years of using a smartphone and today is the first time I have stumbled upon how they work. The explanation is so on point that there is nothing to discard.
Man I've read so much articles on this, and this short 7+ mins video drives the point home better than all those articles. Thanks, now the search ends here.
I am in love with how you teach and simplify all of the problems the most of the student face your genius well done I hope all the teacher and professors out there learn from you
Computer only understand 1 and 0... While youre sending high and low frequency the receiver will demodulate the signal and depending to it's corresponding combination of 1s and 0s the original information will be retrieved . I love how you made the example from analog to digital signal. Thank you 🙏
With the case of AM you said the receiving device has to listen out for a specific frequency. What does the receiving device have to listen out for in the case of FM?
Is the reason they don't just send 0 signal to represent a 0 because then you'd have to constantly be turning the electro magnet on and off which is inefficient and complex or because the receiver will just inteerperet it as a bunch of 1s?
Question, is it possible to exchange the electromagnetic aspect for sound? Instead of using high frequency radio waves use high frequency sound waves? Attempting a project that prohibits electromagnetic anything and trying to have longish distance communication between devices.
It's all fine and solid and it nakes sense if there was only one receiver and one transmitter but that's hardly the case. If two devices are sending radio waves at the very same frequency how do you how which is which?
Reminds me of a fishing date, if you find or have a decent lady, rapalas are decent, yet the mainly have treble hooks, strike king might be better, now worms with a lady, not sure how that would turn out, if your a vegan a model car would be good clean fun. Thankyou for the very informative video young man.
I get how this can send information and the fact the receiver can get these bunch 0 and 1 to "build" files, pictures etc... what I don't understand yet is about our voice. I mean, how 0 and 1 can differentiate my voice from your voice and etc... and music is so complex so much stuff at the same moment... why aren't all voices on FM radios like robot voices? I can't find nobody explaining this part in a simple way yet
What happens to the electrical signal as it reaches the radio wave? Does it generates a high frequency electrical signals and low voltage or maybe I'm mistaken?
Nice explanation! But I don't get how cell phones can modulate the frequency to encode information without 'falling out' of the frequency range it needs to identify the network? Like 'in the 2.4 Ghz range' and all that.
I just wonder how cell phone sent infomation to telephone stations. I mean the energy of cell phone is so much lower than telephone stations. How can telephone stations can get the wave infomation from cellphone ? Thanks you in advanced
202 base station transciever the bandwidth is determined via em frequency e.g 300mghz and amount of channels each packet can hold..2G network uses a 6 digit numeric algorithm each digit represents a band each packet holds upto 52 analog frequencys (1001101) each of these frequencys represent a byte of data. Wavelength depicts the amount of compressed packets sent..via each em burst there are 6 packets comprising of 308 bytes of data sent every second all tellecomunications and satelite work off dilated time burst which intra connects the globe My father Andrew Brian Johnson invented the 202 base station transciever from 1989 the first wireless digital data transciever in the world..
Noah Villareal a device having a designed resistance to the passage of an electric current. Is the meaning right? So with millions of people talking across the world from each other how are there only two voices singled out. What are sound waves hooked on too to travel that far of a distance.
Hello, Could you please let me know the modulation scheme to be used for the following requirement "The system must convey telephone quality voice, photographs and 2-way 1kbit/s data: Carrier frequency should be 1 GHz Thank You
How many Hertz are the waves modulated by in fm? Also, is this how WiFi routers transmit data in homes and such? It seems like not a lot of data can be transmitted if it’s like Morse code. And can radio waves on specific frequencies be time delayed to create digits? If so, is that better than actually changing the frequency? So many questions.
Thanks for this but i still dont understand how the sound wave is attached to the carrier wave. Please put me right on this. A sound wave enters a microphone and the vibrations are converted to EM waves. These EM waves by means of modulation are loaded onto carrier waves(but how?)and the carrier waves are sent out to be picked up by antennae and the process is reversed so you hear sound at the receiving end. I am nearly correct?
How does my phone know which of these signals to take in? Like let’s say on a 2.4ghz wifi there’s 2 devices downloading how do they not jam each other overlapping? Or is there a slight difference in frequency between device A and B used?
I have same question. My friends says there is code known to both transmitters and receivers. I have many questions regarding this process? Why do we use optical fiber when we have electromagnetic waves?
@@motichandmotichand1051 we use fibre optics to channel the electromagnetic waves. The fibre traps the light with total internal refraction and send light from one end to another without any light escaping
