Abstract

COMPONENTES DE BLOQUEIO PARA FILTRAGEM DE UM SINAL. Uma aparelhagem que inclui um amplificador configurado para receber um sinal de entrada. O amplificador principal é também configurado para gerar um sinal de saída. A aparelhagem inclui ainda um trajeto auxiliar configurado para desviar a fase do sinal de entrada gerando um sinal de cancelamento para reduzir ou cancelar o componente de bloqueio do sinal de saída.
