      I watched this video trying to figure out what "modulation" was, and this comment literally just blew my mind. Thank you for teaching me AM stood for Amplitude Modulation, and FM was Frequency Modulation. Until literally this point, I thought it was just some fancy Latin jargon or something, so I just let it go. Thank you.

    Very helpful for newbies like me to understanding AM and FM modulation. But I have a question: For the original AM radio, I grasp that the radio dial would adjust the carrier _frequency_ (in kHz) to "tune" to a broadcast radio "band", and the circuitry would demodulate out the amplitude of the original source signal (prior to modulation, i.e., signal combination). Good so far. But for FM... I'm a bit confused. If _frequency_ is again used as the carrier signal to enable "band" selection (this time, in MHz), but now the source signal *also* uses frequency and is combined or "modulated" with the carrier signal, and has the effect of slowing down or speeding up the overall frequency of the carrier signal... then my question is, how can a radio tuned to a very precise radio frequency, say "98.9 MHz", not experience cut outs when the combined signal drops in and out of that specific band frequency?
    Stated slightly differently, with AM, while the amplitude of the overall signal is modulated to encode the source signal with a higher and lower amplitude. But it still remains locked to a set carrier frequency. Thus, a radio can "tune" into that set frequency and the proceed to demodulate out the source signal. But with FM, if the overall frequency is shifting around due to the combined carrier and source signals modulating on frequency instead of amplitude, how can a radio "lock onto" a set radio channel or "frequency" if the frequency its self is changing due to modulation?

    Great video. Computer modems for telephone lines (I am not sure if hardly anyone uses them anymore) are modulators and demodulators getting the digital binary language of the computer off of an analog telephone signal. The sound that you would hear if someone picked up another telephone in another room on the same line (weird sound) I believe would be the audio representation of those 1's and 0's.

    In AM or FM, the source signal (sound) contains both volume changes and frequency changes. I've never been clear how AM or FM encode for both. Amplitude changes are kind of obvious, but frequency changes? Not so much. Does this have to do with bandwidth? How do two frequencies get modulated? It can't be just the amplitude of the carrier, can it?

    • @troys6965
      @troys6965 2 роки тому

      If I understand correctly, in FM, the broadcast frequency is the center of a small frequency bandwidth. Within that bandwidth, the frequency (rate) of deviation of the center frequency corresponds to source frequency. The amount of frequency deviation from the center frequency corresponds to source amplitude. It helps to think of it in the frequency domain as well as the time domain.

    • @IllidanS4
      @IllidanS4 2 роки тому

      Modulation is changing the property of one wave (the carrier wave) based on the *value* of another wave (the signal). The value of a wave as a function of time is the immediate displacement of the oscillator that produces the wave, but frequency or amplitude are properties of the whole wave, or at least a local region of it around a specific point in time. You don't need to "encode" properties of the function like the amplitude or frequency, you just encode the function itself, as variations in the amplitude or frequency of the resulting wave.

  • @PascalGienger
    @PascalGienger Рік тому

    The superposition actually was used - to encode color on top of the luminance signal of television/video. The phase shift from the reference ("color burst") at the beginning of each video scan line was the tint/color, the amplitude of the added color frequency was the color intensity ;-)
    That's why old black and white televisions without a color frequency filter showed checkerboards and moirée patterns when receiving a color signal...

    • @harrysmbdgs
      @harrysmbdgs Рік тому

      I came to ask my own question but this one really got me thinking!
      I may be wrong, but I believe the modulation is happening to the light output (voltage / frequency shifts), rather than the actual photons of light or the wavelength. Bear in mind that wavelengths of light are orders of magnitude shorter than audio / radio and shouldn’t be a factor when considering either of the modulation frequencies. Obviously more light means more photons, but my thinking is that the LED chip in the torch will naturally have its own combination of wavelengths being emitted, which the circuitry can’t control. I imagine this would vary slightly depending on the output power, ambient conditions, etc., but I don’t think a solar panel should be able to distinguish between these in such a manner.
      I think if our eyes were infinitely sensitive, we would be able to see the brightness of the light varying very slightly as the modulated signal is transmitted, in the same way many LEDs use PWM to effectively dim. If photons or the wavelengths of the torch light were being altered, the variation would be seen in the colour of the light, rather than the brightness.
      Again… I think! 😂

      @homoevolutus 3 роки тому

      A couple of reasons to modulate a higher frequency carrier wave would be to transmit the signal farther and also the antennas can be smaller. The higher the carrier frequency (the one you are modulating) the smaller the antenna can be. For example, a 1 MHz signal has a 1/2 wavelength (for dipole antenna) of 468 feet vs a 1GHz signal with a 1/2 wavelength of .468 feet (~14.3 cm). In his case the antenna is the size of light waves ... so, pretty small!
