Implementação de um Transmissor FM Totalmente Digital em FPGA

Abstract

Resumo-Este artigo apresenta a implementação de um transmissor FM (mono) totalmente digital em FPGA, utilizando os algoritmos coordinate rotation digital computer (CORDIC), cascaded integrator comb (CIC) e high-pass sigma-delta modulator (HPSDM). O transmissor FM digital é sintetizado em um FPGA, simulado seu comportamento e seu funcionamento é avaliado em um kit de desenvolvimento. Os resultados experimentais obtidos mostram o funcionamento adequado do transmissor FM implementado. Palavras-Chave-CORDIC, FPGA, HPSDM, Transmissor FM.Abstract-A fully digital FPGA implementation of a FM (mono) transmitter using the CORDIC, CIC, and HPSDM algorithms is demonstrated here. The FM transmitter is synthesized on an FPGA, its behavior is simulated and its hardware implementation is evaluated on development kit. The experimental results obtained show the suitable performance of this FM transmitter design and implementation.

Analyzing human factors and complexities of mining and O&G process accidents using FRAM: Copiapó (Chile) and FPSO CSM (Brazil) cases

“…Comparing these two different industrial areas, in a range of more than one hundred years of technical evolution, the O&G industry has developed a capability of drilling, production and processing in places ranging from coastal shallows, swamps, deep water and ice, all over the continents. In another hand, and not so differently, the mining industry has implemented mining sites in almost all the lands of the planet, and even considering out of it, 1 having considerable diverse and extreme work environments, such as glacial tundra, tropical forests and inhospitable deserts. The technology applied in mining equipment and process includes UAV‐assisted (unmanned aerial vehicles) to assess and obtain data in remote and dangerous sites, using photogrammetry and heavy process of information and image rendering 2 .…”
