The modulation order of a first type of a modulation scheme and a modulation order of a second type of a modulation scheme form the hybrid modulation technique.
If selected, the sonic energy may be modulated by means of frequency modulation, amplitude modulation, phase modulation, and/or combinations thereof.
The modulation may be amplitude modulation or phase or polarity modulation, and is preferably both amplitude and phase or modulation.
According to the invention, various modulation methods, such as HF modulation (high-frequency modulation), amplitude modulation or phase modulation for instance, are possible.
A signal is generated in the external module by modulating an input signal using pulse modulation and then further modulating the pulse modulated signal using digital modulation.
By applying a modulation voltage, a modulation current flow is generated over the modulation layer.
The modulation parameter settings may include modulation type, modulation symbol rate, and the like.
The modulating mechanism includes an array of modulating components where each modulating component has a pitch.
The apparatus includes a modulating mechanism having a first modulating component and a second modulating component.
The modulation state of the micromirrors by the modulation control signal includes modulation by oscillation of the micromirrors.
The first modulation combined with the second modulation provides substantially null residual amplitude modulation of the beam of radiation.
