O protótipo elaborado com componentes discretos apresenta operação compatível com um circuito típico de PLC. Os circuitos de acoplamento com a rede elétrica são amplamente discutidos. O sinal digital serialmente transmitido passa por um deslocamento de nível que permite ajuste de ganho e deslocamento do valor de sinal, posteriormente sendo aplicado a um VCO que possibilita efetuar de forma simples a modulação do tipo FSK contínua. Medidas de taxa de (BER) foram efetuadas e o resultado mostrado numérica e graficamente. Um circuito integrado monolítico para o VCO, parte do sistema, foi projetado, prevendo uma integração futura. Para isso foram feitas simulações no simulador de circuitos ADS e após no fluxo de projeto foi feito o layout do circuito integrado usando ferramentas de EDA Cadence. O design kit utilizado foi da foundry AMS, tecnologia AMS C35 e mostra a viabilidade de integração de todo o sistema num único CL. / Abstract: It was developed in this work a circuit for power line data communication - PLC that enable low speed data transmission in a circuit topology that enable a future integration. The built prototype was elaborated with discrete components and exhibits a compatible operation with a typical PLC circuit. The coupling circuits with the mains wires are extensively discussed. The signal to be serially transmitted pass through a level shifter that allows a level and offset adjust of the signal, later being applied to a voltage controlled oscillator - VCO that performs the continuous FSK modulation in a simplified way. Bit Error Rate (BER) measurements were made, and the results presented numerically and graphically. A monolithic integrated circuit for the VCO, part of this system, was projected foreseen a possible future integration. For this task was performed simulation in the ADS circuit simulator and later in the project flow an integrated circuit layout was made using Cadence EDA tools. The chosen design kit comes from AMS foundry, in the technology AMS C-35, and shows the system integration viability in a single integrated circuit. / Mestrado / Eletrônica, Microeletrônica e Optoeletrônica / Mestre em Engenharia Elétrica

Bezdrátový přenos letových údajů z letounu na krátkou vzdálenost / Wireless transmission of flight data for low distance

Kučera, Petr January 2009 (has links)
This diploma thesis deals with the flight data wireless transmission from aircraft to the ground station. This is the data sent from the acrobatic aircraft during races, specifically the GPS position and data from sensors of acceleration and rotation of the aircraft. It dealt with the theoretical analysis of the radio link and design of device that receives radio transmission. In aircraft it is dealt with data capturing and their deployment through the radio module. Data are sending to another post-processing on the ground station after receiving. There are two solutions of radio module and in the last part is a solution for capturing data from more airplanes.
