How I would like to change the cell phone industry [was AM electromagnetic waves: 20 KHz modulation frequency on an astronomically-low carrier frequency]

I was not aware there was a compelling reason for analog cell phones to stop using FM. Sounds like a solution looking for a problem. FM audio is boring -- no entertaining high-pitched tones from solar prominences which would definitely be heard on AM audio. OTOH, AM video is boring. FM video is better. As I said before, the Y [luminance] signal should be carried on an FM wave rather than an AM wave. Analog radio-frequency audio devices should use AM. Analog radio-frequency video devices should use FM. |
