| Oct 22, 2020 at 12:43 | comment | added | Lewis Kelsey | It have not seen it to refer to line coding of a generic bit stream tbh, but instead that it consists of the samples of the analogue signal. So my final consensus is that it mainly refers to line coding of a serialisation of samples from an analogue signal. There is a terminological confusion on this in the literature and I have to know exactly what a surface level classification refers to, which can often actually be a difficult task even when you know the low level details | |

The general consensus I'm arriving at is that it's mainly 5), the 'modulation' word being as if it were the modulation of the analogue signal with another signal in the analogue domain to give the digital signal output | |

| Oct 22, 2020 at 10:34 | comment | added | Lewis Kelsey | @MarcusMüller Well I just thought that the term 'modulation' was a bit of a misnomer for 1), same for Digital PAM, because it's not really 'modulation',because there's no carrier to modulate. It's like how digital PAM only becomes APSK when a carrier is involved. Digital pam is a bit like saying modulating a series of pulses with a binary sequence, whereas PCM seems to be 'modulation that transforms into a binary sequence' which seems to be loosely, 'modulation with a Dirac comb' or in the case of 3, 'modulation with a binary sequence ' again | |
