Resumo: | This work presents a theoretical and practical study of frequency synthesis techniques known as phase locked loop (PLL) and Direct Digital Synthesizer (DDS). The objective is to describe characteristic principles of two conceptions through a process of observation and comparison, identifying the better option for transmission equipment of digital signals for televisions. The chapters create divisions of the theories and practices with the aim to facilitate the development. They were established and validated with characteristic principles of a frequency synthesizer those that are directly related with the error rate of bit in a communications system and those made possible are within the established standards of government inspection agencies. The more required characteristics are the high spectral purity, the low phase noise, the high precision and exactly of synthesizer signal. Keywords: frequency synthesis, PLL, DDS, transmission equipments, digital signals for televisions. |

O objetivo ? descrever as principais caracter?sticas das duas concep??es atrav?s de observa??o e compara??o, identificando a melhor op??o para transmissores de sinais digitais de televis?o. Os cap?tulos foram divididos em abordagens te?ricas e pr?ticas, visando facilitar o desenvolvimento. Foram estabelecidas e avaliadas como principais as caracter?sticas de um sintetizador de freq??ncias que est?o relacionadas com a taxa de erro de bit em um sistema de comunica??o e as que possibilitam o sistema alcan?ar os padr?es estabelecidos pelos ?rg?os de fiscaliza??o do governo. As caracter?sticas requeridas que mais se destacam s?o a alta pureza espectral, o baixo ru?do de fase, a alta precis?o e exatid?o do sinal sintetizado. Palavras chave: s?ntese de freq??ncia, PLL, DDS, transmissores, sinais digitais de televis?o.Submitted by Tede Dspace (tede@inatel.br) on 2016-09-14T14:06:11Z No. of bitstreams: 2 license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5) CAPA_Rodrigo Ot?vio Rocha Cardoso_revis?o.pdf: 3906527 bytes, checksum: 1baec6519a3cdaa4f436f46cad608652 (MD5)Made available in DSpace on 2016-09-14T14:06:11Z (GMT).
