Understanding Frequency Modulation 

Thank you!

Thanks!

Bruh ur username 😭😭💀

Modulation involves changing some property of the carrier (in this case, its frequency) based on the modulating signal - they're not really "added" together. In the case of FM, a special device called an FM (de)modulator is used. The actual details of how the carrier frequency is changed by the modulating signal (and how the modulating information is recovered at the received) is somewhat beyond the scope of this introduction, but there are many, many sources of information on this if you'd like to deeper. [Incidentally, there are multiple different techniques for demodulating an FM signal, e.g. quadrature, PLL, etc.]

(laughs) You know, I've watched Afrotechmods many times and I never really noticed the similarity until you mentioned it. But no, entirely different person - I do all of my own recordings myself, for better or for worse :)

Purely analog phase modulation is pretty rare, but I did make a video about Phase Shift Keying as well as one on APSK and QAM :)

Not nitpicking at all, just something I didn't have the time to go into in this video :)

It's infinite

We do not have a dedicated playlist on that topic, but you might find what you are looking for in different videos on our channel.

Trying to understand Diva Vst here...

xD

Yup, Reface DX owner here. Also pretty good: www.sfu.ca/~truax/fmtut.html

As you've all probably noticed, this video is really more about FM in the radio frequency domain, not the audio domain :)

@@pauldenisowski Still useful to visualize. Also when you thing of the sidebands as harmonic content it all fits. Unless I completely missed the boat ^^

Now I understand - you meant the usable audio spectrum - yes that is 15 kHz and the first FM radios had it even lower (13-14kHz) to have their rather bad analog low pass filters to mask out the pilot tone. I love FM. I built my own FM stereo receiver 1986 at age 15. And when disabling the stereo decoding and low pass - you could record the mono FM signal on a tape machine and actually hearing the pilot tone when running the tape at half speed...
