Good day! I understand that this might be a stupid question, I looked on the internet but I couldnt find it. Can someone please clerify for me, how exactly is a digital signal transmitted. I hear that the digital signal is better, it has more frequencies and everything is passing on digital technology. I understand that an analog signal is just voltage applied on an antenna, the shape of the antenna and the parameters of the signal determine the length of the magnetic field. After that we have another antenna which will catch the signal and amplify it.
How does that work with a digital signal, is the digital signal just square impulses? Whats the difference between an analog antenna and a digital antenna, how come there are more frequencies, is it just frequency modulation of an analog signal? I dont get it, what exactly is a digital signal transmission?
