Abstract

Un generador doptico de senal de ventana que inicia la generacion de una senal optica de salida como respuesta a un impulso de activacion optico, y quefinaliza la generacion de una senal optica de salida como respuesta a un impulso de desactivacion optico. El tiempo de subida de la senal optica desalida es igual al tiempo de subida del impulso de activacion optico, y cuyo tiempo de bajada es gual al tiempo de subida del impulso de desactivacionoptico.A doptic window signal generator that initiates the generation of an optical output signal in response to an optical activation pulse, and which finalizes the generation of an optical output signal in response to an optical deactivation pulse. The rise time of the desalted optical signal is equal to the rise time of the optical activation pulse, and whose down time is equal to the rise time of the optical deactivation pulse.
