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.'' OPTICAL WINDOW SIGNAL GENERATOR AND PROCESS TO GENERATE AN OPTICAL WINDOW SIGNAL ''. An optical window signal generator that initiates the generation of an optical output signal in response to an optical activation pulse and ends the generation of the optical output signal in response to an optical disable pulse. The transition time of the optical output signal is equal to the transition time of the optical activation pulse, and its drop time is equal to the activation time of the optical disable pulse.
