Very good video. I am making a video right now where I have to explain bandwidth to a layman. This is hard to do without visuals like you have shown, you did a great job explaining it.
Wow thank you so much for this video, your video. I have an old Kenwood ham radio that I'm experimenting with am bandwidth. It is around 10 khz and now I know how it really sounds. It's am broadcast quality not bad for a poor boy.
Great video, particularly because you highlight the two active frequencies either side of the carrier. I am struggling to understand this. Are these + and - of the same tone frequency, or duplicate single frequencies? I believe AM creates duplicate side-bands so you can listen to one or the other. Also, in FM bandwidth I assumed the low tone frequencies would be lower than the carrier and high frequencies higher, but the examples I've seen also form a peak at the carrier with what appears to be mirrored signals either side of it. Please excuse long, dumb question.
If larger bandwidth is better, why would anyone want a smaller bandwidth? Does it save battery or energy? Does it reach farther? What are the benefits of having smaller bandwidth?
Lower noise pickup is one reason. This isn't something a broadcaster would worry about too much, but for other communication purposes, noise can be a problem and the amount of noise received is proportional to the bandwidth... therefore less bandwidth equals less noise and higher likelihood of hearing a weak signal. The full bandwidth I demonstrated with the music is great for fidelity of the music, but unnecessary for other communications like, for example, voice where 3000 Hz audio is plenty. Hence the AM bandwidth for this would be +/- 3 kHz or 6 kHz total rather than the +/- 10 for the better sounding AM music example. Because lower noise situations can hear weaker signals, yes it does reach farther.

That was very informative!
Dude, this video was awesome. Helped me explain bandwidth to my wife in record time.
Thanks for watching. I'm thrilled it helps explain the basic concepts of radio bandwidth.

@@SkyCharter how about energy consumption? Is that effected?
