Abstract

En un sistema de transmisión de impulsos eléctricos una disposición eléctrica para generar una onda portadora modulada en fase o frecuencia que comprende medios para modular asimétricamente de acuerdo con una onda de señal, la duración de los impulsos de un tren de impulsos eléctricos regularmente repetidos y medios para extraer uno de los componentes armónicos del tren de impulsos para servir como dicha onda portadora modulada.In an electrical impulse transmission system an electrical arrangement for generating a phase or frequency modulated carrier wave comprising means for asymmetrically modulating in accordance with a signal wave, the duration of the pulses of a train of regularly repeated electrical impulses and means to extract one of the harmonic components from the pulse train to serve as said modulated carrier wave.
