Abstract

''GERADOR DE SINAL DE JANELA óPTICA E PROCESSO PARA GERAR UM SINAL DE JANELA óPTICA''. Um gerador de sinal de janela óptica, que inicia a geração de um sinal óptico de saída, em resposta a um pulso de ativação óptica, e termina a geração do sinal óptica de saída, em resposta a um pulso de desativação óptica. O tempo de transição do sinal óptico de saída é igual ao tempo de transição do pulso de ativação óptica, e seu tempo de queda é igual ao tempo de ativação do pulso de desativação óptica.
