Hello, I am trying to understand how analog video recording works. It uses FM, where deviation corresponds to brightness, side bands correspond to the level of detail. I guess it is similar to FM radio, where deviation corresponds to loudness, side bands correspond to audio frequency bandwidth. So I expected that as intelligence amplitude increases, the carrier frequency should increase, but you show that the overall bandwidth increases. As intelligence frequency increases, I would expect side bands to increase, this makes sense, as this frequency is added or subtracted to carrier zillion times, gradually decaying. So, could you clarify why you show that bandwidth gets wider with the increase of the intelligence amplitude instead of the carrier moving to the right? Thanks!
Excellent explanation! Thank you!
a tip: watch series on Flixzone. Been using them for watching all kinds of movies lately.
@Terrell Braxton yea, I've been watching on flixzone} for years myself :)

What software are you using to plot the frequency spectrum? Great video by the way, thank you for posting.
Thank you!!
