La " modulation d'amplitude en quadrature " (soit Quadrature Amplitude Modulation, ou QAM, en anglais) est une forme de modulation d'une porteuse par modification de l'amplitude de la porteuse ...
Ferroelectrics are commonly used in electrical devices such as random access memory, capacitors and piezoelectric actuators 1,2. Other important applications of ferroelectrics are based upon their ...
The design strategy for terahertz metasurfaces capable of achieving spin-selective functionality through complex-amplitude modulation is systematically categorized into four distinct parametric ...
As our society’s hunger for data grows—not only more data, but more data delivered faster—older modulation schemes based on NRZ-type encoding grow increasingly inadequate. We need to get data from ...
