| Jan 15, 2020 at 22:58 | comment | added | cinico | @Reinstate Monica - ζ-- I was not trivializing, just focusing on differences. As I said, before knowing that the adapters actually transmit packets of data, and not the direct signal, my hope was that it would work because the frequencies could be similar. | |
| Jan 15, 2020 at 21:50 | comment | added | nanofarad | @cinico For transmission purposes, the "only" difference of waveform and frequencies is actually a massive one that ought not be trivialized--even if I had an analog modulator that upconverted some baseband analog signal and injected it onto power lines, I'd still be hitting tons of issues. This is where the phone-over-powerline issue comes up, since it has a lowpass characteristic which is fundamentally incompatible with ADSL. | |
| Jan 15, 2020 at 15:53 | comment | added | LPChip | @cinico In terms of electricity, analog vs digital is very different too. In electricity, analog is a constant flow of electricity where its intensity fades in and out creating a waveform. In digital signals, these are pulses of on and off being fired at a specific interval. The very first series of pulses in a digital signal is the handshake, which is meant to establish that communication is possible. Analog does not handshake, thus a digital input will never understand an analog output. | |
| Jan 15, 2020 at 14:44 | comment | added | cinico | @LPChip I know the difference. I mean for transmission purposes (not for processing) the only difference could only be the waveform and the (range of) frequency(ies). | |
| Jan 15, 2020 at 14:25 | comment | added | LPChip | @cinico a digital signal vs analog signal is not just sine vs square waveform. It will look like that, but the difference is significant. A digital signal is a set of instructions on how to recreate the analog signal. By standardizing the digital signal, it is possible to remove a lot of data from the digital signal as such that more data can be fitted at a place such that higher speeds are possible or lower bandwidth is utilized. Look at it from a .wav file vs .mp3 file perspective. If you want more info, search on you youtube.com/watch?v=Y2OPnrgb0pY | |

| Jan 15, 2020 at 13:38 | comment | added | cinico | Thanks. That's what I needed to know. I didn't know that these adapters worked with data packets. I thought that would simply directly transmit a (digital) signal. For that reason, I thought that because the difference between digital and analog is basically the shape of the signal (squared vs sine), maybe the frequency of the signal was not that different between ethernet and phone, and then it could work... I was trying to avoid phone extension cords because of all the work to lay it around the walls compared with this simple potential solution. Thanks again! | |
