Examples

Differential phase-shift keying (DPSK) Differential encoding main Differential phase shift keying (DPSK) is a common form of phase modulation that conveys data by changing the phase of the carrier wave. Source: Internet

The modulated waves are summed, and the final waveform is a combination of both phase-shift keying (PSK) and amplitude-shift keying (ASK), or, in the analog case, of phase modulation (PM) and amplitude modulation. Source: Internet

It can also be viewed as a change of the frequency of the carrier signal, and phase modulation can thus be considered a special case of FM in which the carrier frequency modulation is given by the time derivative of the phase modulation. Source: Internet

The main advantage of SOA is that all four types of nonlinear operations (cross gain modulation, cross phase modulation, wavelength conversion and four wave mixing ) can be conducted. Source: Internet

Digital FM synthesis (using the more frequency-stable phase modulation variant) was the basis of several commercial musical instruments beginning as early as 1977. Source: Internet

Since phase modulation is employed, higher order terms are also generated. Source: Internet
