DENVER — A small startup claiming breakthroughs in phase-coherent filter modulation will be demonstrating its signal-processing techniques in analog pager bands later this year, as a prelude to ...
Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...
L'utilisation des onduleurs multi niveaux contrôlés par des systèmes de commande embarqués permet de réaliser des plateformes de commande robustes, moins encombrées tout en garantissant une meilleure ...
Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...
Optical vector analysis has emerged as a critical tool for characterising optical devices, enabling simultaneous measurement of amplitude and phase responses over wide bandwidths. This technique is ...
The Internet explosion caused a surge in demand for new telecommunication services. The next wave of demand will come from new applications like third-generation (3G) high-speed personal ...
Des chercheurs de l’Institut Helmotz d’Iena ont élaboré un dispositif pour moduler un faisceau laser à l’aide d’ultrasons simplement diffusés dans l’air ambiant, et non plus dans un matériau solide – ...
