Study on Amplitude Modulation Principle of Chaotic System

open access: yesComplexity, 2020
Exploring the amplitude modulation phenomenon of chaotic signal has become a subject of great concern in recent years. This paper mainly concentrates on the preliminary study on amplitude modulation principle of a chaotic system.

Corrected Long-Term Time-Average Sound Level of Amplitude-Modulated Wind Turbine Noise [PDF]

open access: yesArchives of Acoustics, 2023
Amplitude modulated noise from a single wind turbine is considered. The time-varying modulation depth D_m and the short time-average sound level L_Aeq,τ (with τ = 20 s) are measured at the reference distance d_*.

Method of calibrating modulation meter MI 2305

open access: yesVojnotehnički Glasnik, 2000
In this article an original way of calibrating the MI 2305 modulation meter is described. AM traceability is achieved using tree secondary etalons. FM traceability calibrating is achieved by using the Bessel zero method.

Amplify–Quantize–Forward Relay Channel With Quadrature Amplitude Modulation

open access: yesIEEE Access, 2022
This paper considers an amplify–quantize–forward (AQF) relay channel with $M$ -ary quadrature amplitude modulation, where the relay implements a uniform quantization for the amplified received signal and forwards it to the destination. Two

Reconfigurable Mach–Zehnder interferometer for dynamic modulations of spoof surface plasmon polaritons

open access: yesNanophotonics, 2021
We propose an ultrathin reconfigurable Mach–Zehnder interferometer (MZI) for realizing dynamic frequency and amplitude modulations of spoof surface plasmon (SSP) signal.

Autodyne Sensor Signals with Amplitude-Frequency Modulation of Radiation

open access: yesSensors, 2020
A mathematical model of an autodyne oscillator with a combined amplitude-frequency modulation, which is under the influence of its own radiation reflected from the target, is developed.

Coherent amplitude modulation of electron-beam-driven Langmuir waves [PDF]

open access: yesAnnales Geophysicae, 2013
A linear approach to the phenomenon of irregular amplitude modulation of beam-driven Langmuir waves, developed in a previous paper, is extended to explain periodic modulation as well.

Amplitude modulation of radiation by coupled resonators

open access: yesДоклады Белорусского государственного университета информатики и радиоэлектроники, 2020
In this paper, we describe a method that allows one to realize highly efficient amplitude modulation of radiation at the output of electro-optical laser switches with two coupled resonators, in which electro-optical elements are located both in two split
