Figure 3-1. An alternating waveform. Amplitude modulation Possibly the most obvious method of modulating a carrier is to change its amplitude in line with the modulating signal. The simplest form of ...

The amplitude of the modulating signal controls the amplitude of the carrier frequency, as well as that of the sidebands, in the resulting spectrum. The strength of the modulation is called the depth ...

In this study, we use various signal constellation diagrams to classify signal modulations into 8 modulation types namely, Binary Phase-Shift Key-ing (BPSK),4-Pulse Amplitude Modulation ...

Here, an amplitude-phase-time block modulation (APTBM) scheme and a corresponding demodulation scheme for resisting amplifier nonlinearity are proposed, establishing a new paradigm for balancing the ...

This research work, entitled "Spin-dependent amplitude and phase modulation with multifold interferences via single-layer diatomic all-silicon metasurfaces," was published in Volume 4 of Opto ...
