How I would like to change the cell phone industry [was AM

how would u like to change the cell phone industry? Analog cells phones should stop using FM and should start using AM with SHF frequencies - at least 3 GHz and at most 30 GHz. 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. |

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

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. |
