Being a famer I have an electric fence and you could hear the ticking on my medium wave radio and much louder tick on my long wave band, it does not affect FM wave at all.
Morse code is still used. Those with a short-wave radio can easily demonstrate this to themselves. It is very easy to hear most weekends, when contests are in full swing.
People also forget to put down that AM/FM portable radios are more reliable then electricity and internet if your cell phone don't work cause low battery or has no internet or electricity most of the modern ones can be powered by battery as well as solar power, crank, and most modern ones can charge phones act as light or even use a SOS beacon for getting attention .Good for on the go or tight situations and good way to get information quickly no matter where you are located and easier to operate. With so many different devices it makes it super easy to receive information and communication no matter where you are at and no matter what circumstance. Not only it paved way for information age but it also can save lives such as u know a pandemic ya see here.
Awesome video. Although, I'm still a little confused on how audio (or any media type) doesn't get distorted when "packaged" inside different sine wave lengths.
I’m a beginner in this field but here’s my understanding. The radio transmitting your voice will take a certain amount of measurements as you talk. The number can depend on the type of modulation, encoding scheme ,and frequency. You can hear a dramatic change in quality as the frequency gets lower because there just not as many waves to carry your information. If you wanted something crystal clear you would need to use TCP, look up osi layer 4. To answer your question, the sine wave is technically the information. The sine wave is being interrupted to mean either a zero or one, nrz is something to look up that will help you understand. Even as the frequency changes the sine wave is still a wave that can be interpreted. Sorry for the rant drunk scrolling TH-cam but if you have more questions I’m here
it is purposefully distorted in a way we can control into a format better suited for transmitting and receiving. the "distortion" is actually the encoding. when the package is received, decoding then happens and you get the original, undistorted data. also the quality of that data depends on things like noise and interference during transmission. you can think of human readable data being converted into 1s and 0s (based on an agreed/standard code between both ends) and then letting those binary values dictate the frequency or amplitudes of the transmitted waves. then those waves get turned back into 1s and 0s and then back into human readable data on the receiving end. with both ends using transducers and/or digitizers to achieve this.
It was really helpful. I cnnot describe my felling when i finally understood the radio's working method. Just hats off for understandable description. 😊
Incredible how fast radio waves travel instantly nearly at speed of light. Amazing drones can be real time flown in other side of planet. And that computer processes can computer all of that so fast as well. How do the processers computer so fast, AND how are they made or constructed to do so?
I’m no expert, but its just how fast electricity travels, which is close to the speed of light, making the computations instant. How it’s made is another story, and requires millions of small parts the size of cells that all fit together to process electricity.
@@FAB1150 kind of..but not necessarily the same thing..light is visible a form of rf and interacts differently than other forms of rf like infrared,microwaves depending on conditions..I think 🤔..
@@michaelgaeta3151 no, it is exactly the same thing! At different frequencies they behave differently (for example, you can't see it anymore) because the amount of energy it stores changes, and at some point (for example x-rays), the waves become so small that they zip right through less dense objects, like your flesh.
watching that part with the glitch effect and the beeping morse code is actually kinda creepy if your watching this at 2 in the morning, but great video, loved it
First of all, thanks for the information, and second, TRABANT!!! The car you used was a Trabant 601 (maybe), and was a car from the DDR, east Germany. MfG Johannes H.
Wait, if you need frequency to distinguish one radio station from the next, how can they modulate frequency to transmit information? If I tune my radio to one frequency and the station modulates its frequency constantly to transmit information, wouldn't it constantly fall in and out of the frequency I tuned my radio to? Or do I tune my radio to a RANGE of frequencies and the modulation stays within that range?
That range is also known as bandwidth. And that bandwidth (for FM in the US) is 200kHz, or 0.2MHz around a center frequency. So, if your radio is tuned to 100.5 MHz, then the range (bandwidth) is 100.4 MHz - 100.6 MHz. That's why FM station frequencies are always 99.7, 99.9, 100.1, 100.3, 100.5, etc.
and they just sussed how to send electricity through wifi bit like nikkoli teslas invention but better cant wait to see how that pans out, cheers great vid again mate
I feel like he would be proud. We technically use his idea of electromagnetic powering of devices with smart watches and such. And while he’d be disappointed that we don’t use it for long range electrical transfer, I bet he’d be impressed with how much info we get from it just by using so many different frequencies to transmit on different channels and then have high speed encoders and decoders to transmit large amounts of info using electricity faster than he ever could have imagined.
If different radio channels are only allowed to use a specific frequency, how is frequency modulation possible? If you change the frequency of your sine wave, shouldn't that interfere with other channels?
you are basically given a range of frequencies you can use for one channel, this range is called the bandwidth, and FM varies only within this bandwidth.
"You're exciting electrons on the transmitter side. . . which is received as a signal. . ." Not exactly. Electrons aren't flowing between the transmitter and the receiver. Electromagnetic waves are. Electrons are only flowing through the metal conductors and metalloid semiconductors of the transmitter and receiver,.
I'm concerned with the fact that this video encourages children to mess with electrical gadgets without warning them of the risk. JK. I loved this video. It was really helpful. :)
You don't even need a coin and a 9 volt battery. Simply turning on a lightswitch, that is 1-2 meters away from the radio, already can be heard on a static station (the empty noise gap between radio stations).
I though the morse code would say something along the lines of 'please like and subscribe' but alas I was wrong lol 😁😸 Very interesting video nonetheless
I'm concerned that I spent more time deciphering the final morse code message than I did watching the video. Been meaning to learn it but having a cheat sheet is just as good if just a bit more time consuming.
This doesn''t explain how the waves actually carry the sound (specific sound you're sending off with it such as music or your voice, not the electrical sound) through the air (and you don't hear it with in that air it is traveling throuhg) then it comes out some source (a radio) and you hear it
That's because they _don't_ carry sound. Rather, they carry _information._ It's up to the transmitting device to encode the information from sounds into binary strings that can be represented as AM or FM signals and them the receiving device has to translate that information back into sound waves.
But when you are tapping the coin on the battery and the radio has turned the signal to audio do you just speak and the you will hear your voice from the radio
So basically we "translate" the soundwaves into radiowaves which can travel much larger distances, some device can receive these radiowaves and translates them back into the soundwaves we can hear? But what I dont understand, how exactly is the radiowave changed so that it has the information of our sounds? I mean if the frequency isnt changed, what is? I thought sounds are just "ups and downs" so how can you translate these ups and downs into radiowaves without making the radiowave going "up and down" (keeping the frequency) Or did I get something completely wrong?
So, mobile phones are technically their own Modem (MODulator/DEModulator). Secondly, I'm sure you're aware that you could have said 680 kHz (kilohertz), as opposed to 680,000 Hz (Hertz).
They're three dimensional. Also, up and down is really back and forth (maximum to minimum energy, and back up again, and so on). Oh, and each frequency/wavelength combination would be a color we can't even begin to imagine. Same with infrared, ultraviolet, etc.
So if you could send signals to all frequencies. So can you receive all signals at once ? A way to decode??? Cosmic background radiation ? The difference and their info in each layer of emf.
Uhm so I do know that radio is resonating on its own frequency but what about the phase difference like is 500 hrtz start first on some pico second pls explain more. The thing I don't understand is how do radio able to ignore all frequency and able to collect that frequency even they has different phase

Being a famer I have an electric fence and you could hear the ticking on my medium wave radio and much louder tick on my long wave band, it does not affect FM wave at all.
This is because the spark creates a rough amplitude spike, an fm reciever is deaf to a spike in amplitude
