Abstract

Procedimiento y dispositivo para el control automático de realimentación negativa de equipos electrónicos, en los equipos cuya salida es una señal o una radiación electromagnética modulada por impulsos organizados en secuencias aleatorias de formas de onda con retorno de cero, de misma probabilidad y estadísticamente independientes, caracterizado porque una parte de la señal o de la radiación electromagnética saliente del equipo a controlar es tomada y demodulada de manera a obtener la señal envolvente, que es filtrada para obtener sólo la componente con la misma frecuencia de repetición de los impulsos, demodulada e integrada de manera a obtener una señal proporcional a la potencia pico a pico de la señal o radiación electromagnética, en el curso de estas operaciones siendo previstas una o más fases de amplificación que permiten a la señal proporcional a la potencia pico a pico de mandar en realimentación negativa el equipo a controlar.
