How to calculate modulation index by formula We use the following modulation index equations to find the variation between the message and the carrier signals: Amplitude modulation index The definition of AM modulation index is the amplitude ratio of the message signal to the carrier signal: μa=...
It is instructive to study the modulation of one sinusoid by another. In this section, we will look at sinusoidal Amplitude Modulation (AM). The general AM formula is given by where are parameters of the sinusoidal carrier wave, is called the modulation index (or AM index), and is th...
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 ...

Holographic films contain a copolymer binder having the following formula:(M).sub.w (VAc).sub.x (VOH).sub.y (CTFE).sub. zwherein M is a fluoromonomer; VAc is vinyl acetate; VOH is vinyl alcohol; and CTFE is chlorotrifluoroethylene; and wherein w, x, y, and z are percentages by ...
- Modulation index (μ) = 0.5 - Power of the carrier wave (Pc) = 60 W 2. Understand the Formula: The power in the upper side band (P_USB) can be calculated using the formula: PUSB=Pc⋅μ22 3. Calculate μ²: - Calculate the square of the modulation index: μ2=(0.5)2=0.2...
(3)(QuadratureAmplitudeModulation) A modulation technique that employs both phase modulation (PM) and amplitude modulation (AM). Widely used to transmit digital signals such as digital cable TV and cable Internet service, QAM is also used as the modulation technique in orthogonal frequency division ...
aThe modulation index M can be used as an indicator of the current regulator saturation,when it approaches M=1. So by setting the threshold value of the modulation index close to 1,in the FW algorithm, the saturation of the current controllers can be overcomed. 当它接近M=1时,模块化索引M...
