The question that this essay is concerned with is: if 'modulation' is central to the concept of control societies, then what exactly is modulation, and how does it operate?
However, the concept of modulation needs to be further complicated, in order to fully understand its relations to control societies.
The considered modulation formats are PAM 2 to 64 PSK 2 to 64 FSK 2 to 64 and QAM 2 to 64.

When the value of RI contrast becomes larger, obvious grating ripple modulations and bandedge modulations can be found in various frequencies in the TvPC.
Three kinds of modulations (with bandgap center, bandedges, and grating ripples, respectively) are observed in TvPCs, as evidenced in modulation spectra and modulation map, by TSMM calculations.
With the appropriate modulation turned on, the synthesizer will modulate using that data.
For example, if the FSK modulation is set to random access, the synthesizer will randomly step between the two levels.

The simplest discrete vector modulation mode is the constant amplitude, four phase state modulation having the phase plane constellation diagram shown in Figure 2.
It can be seen that the modulation results in a single sideband, suppressed carrier output with a high content of modulation harmonics.
