Thank you so much for these videos, I'm working on my first wireless project right now and these have been a huge help so far. Can't wait for the rest!

Excellent introduction to communication theory! Looking forward to the more detailed presentation of this material. It reminds me of the engineering university courses that I took, 30 years ago. :-)

Unfortunately, at universities, we learned more about this topic 30 years ago than now. That is one reason for this channel.

@@HB9BLA I agree! In the last 10 years, you can get an electrical engineering degree without taking a course in thermodynamics! Just because an EE doesn't use TD daily, doesn't mean that they don't need to understand it. Keep up the good work.

As always an excellent video. One question: after 4:00 you you mention that "the signal has no distinct peaks" (FM modulation). I believe that periodic signals always have a discrete spectrum, and suspect that the discrete lines are not visible due to the bandwidth of the FFT analysis (windowing) (see the broad peaks in the AM modulation example). Maybe you can see the discrete spectrum better if you set the modulation frequency higher. - In addition, with the FM spectrum you probably see another artefact: the spectrum does not always have the same shape, sometimes it is 'flat top', sometimes it is skewed to the right or left. Does the sampling length play a role here? Thank you for your vontinued effort!
@HB9BLA2 жыл бұрын
You are right. If you modulate it with one frequency it also has peaks and my RBW was probably too wide.

At the beginning of the video you refer to bandwidth as a quantity with the physical dimension of hertz. Later you talk about bits per second. How does that fit together?
@HB9BLA9 ай бұрын
Shannon's law (C = B log2< (1 + S/N)) shows the relation between bandwidth B and the highest attainable error-free data speed in bps C.

Gibt es eigentlich gerichtete Antennen für LoRa und ergibt sich ein Vorteil?
@HB9BLA2 жыл бұрын
Man kann Richtantennen für alle Frequenzen bauen. Bei LoRa nützen sie nicht so viel. Ich habe auf meinem Hauptkanal zwei Videos über die Ausbreitung von LoRa gemacht.
