| Nov 1, 2020 at 14:36 | comment | added | hyportnex | The truth is that I am not sure whether your RP Photonics is really about DSB-AM and not PM (phase modulation), but even if PM the conclusion is the same, higher SNR for larger $\kappa$ | |
| Nov 1, 2020 at 14:36 | comment | added | hyportnex | Forgot to add that "modulation depth of a sinusoidally modulated signal can be defined as the modulation amplitude divided by the mean value" should be other way around, that is modulation depth of a sinusoidally modulated signal can be defined as the the mean value divided by modulation amplitude, even this definition is quite lame though. The correct definition of $\kappa$ is by $\eqref{1}$ where $|m(t)| \le 1$.... | |
