for AM, where m(t) is the message signal, fc is the carrier frequency, and a is a parameter called the modulation index. A modulator for either DSB or AM is implemented as a multiplier. If the Fourier transforms of Eqs. (9) and (10) are taken, the resulting spectra are (11)Xc,...
Frequency modulation index can be defined as the ratio of fc/fr [146,147]. This ratio must be an integer value in order to get discrete spectrum comprised of integer harmonic multiple. The amplitude of the reference signal and carrier signals are denoted as Ar and Ac [148]. Amplitude ...
) based on the classical Modulation Index measure of coupling. eMI is suitable both for continuous and epoched data and allows estimation of the statistical significance of each pair of frequencies for phase and for amplitude in the whole comodulogram in the framework of extreme value statistics....

For example, an interface between different refractive indices causes a change in propagation direction of light both in reflection and transmission1. The strength of this effect depends on the difference between the refractive indices Δn and the incident angle6. Large refractive index differences on...
In the outdoor demonstration, the scintillation index (SI) and the Fried’s coherence length r058 are used as figure of merits to evaluate the present atmospheric turbulence conditions. The SI, defined as the ratio of the standard deviation of the intensity σI to the average intensity of ...

In contrast to the CB-PWM methods, where the individual pulse patterns are added to create the Njk* target, on the NLM this set-point is obtained directly from the arm modulation index mjk* as: (4)Njk*=roundNmjk* where N is the number of SMs available on the MMC stacks. In this ...
