In Figure 5-11 the signal points are placed in an array which can serve as an example of quadrature amplitude modulation (QAM) . Figure 5-11. An example signal constellation for QAM. Another way of ...

where A is the amplitude of the wave, C (t) is the carrier signal modulation, and m (t) is the modulating waveform can either be a single tone. This can be represented by a cosine waveform, or the ...

A formal perturbation scheme is developed to determine original modulation equations for laminar finite-amplitude non-linear waves in an incompressible fluid. Three idealized problems are analysed.

This paper presents a comparative theoretical study of amplitude, phase, and frequency modulation. In the first part, the fundamental mathematical expressions for the three types of modulation are ...
