Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The asymmetrical multilevel inverters allow to obtain a high resolution together with a good efficiency thanks to the switch hybridization. Nevertheless, the supplies of the cells must be insulated one from each other, which increases the converter complex ...
The robustness of the delivery of digital compressed video streams has always been one of the main topic of the standardization bodies to assure the Quality of the Service (QoS). The MPEG standard which is nowadays the reference for digital television defi ...
Le but du projet est de réaliser la commande d'un moteur asynchrone sans capteur et d'en évaluer les performances. La plateforme utilisée pour implémenter l'algorithme de contrôle est un DSP (Digital Signal Processor) de la famille 2812 de Texas Instrument ...
In this work we have applied optical pulse-coding technique to spontaneous Brillouin-based distributed temperature sensor (BDTS) based on the Landau-Placzek ratio (LPR). We experimentally show that pulse-coding applied to optical time domain reflectometry ...
Frequency Domain Linear Prediction (FDLP) represents an efficient technique for representing the long-term amplitude modulations (AM) of speech/audio signals using autoregressive models. For the proposed analysis technique, relatively long temporal segment ...

We have recently demonstrated an ultrafast photonic crystal laser and cavity coupled laser array with modulation rates of 1THz at room temperature, a 20 GHz optical modulator with activation energies of 60 Q and a quantum dot photonic crystal laser with la ...
This paper presents a hybrid continuous-discrete-time Delta-Sigma modulator for portable communication systems following a low-power strategy. The proposed design methodology is extendable to different specifications. A multi-bit technique has been introdu ...
Recently there is an increase in interest for using super-regenerative receivers for pulse based communication systems. To receive a pulse using the super-regenerative architecture the pulse needs to be aligned with the zero crossing of the damping co-effi ...

In the first part, a fast and accurate method to compute the harmonic spectra of PWM modulators is presented. This method allows to compute all measurements based on the harmonics values such as the THD or FWTHD. It is especially advantageous for multileve ...
