Abstract

Mejoras en, o relacionadas con, sistemas eléctricos de comunicación de modulación por impulsos caracterizadas por un sistema eléctrico de comunicación por impulsos en el que las señales están transportadas por impulsos de forma invariable, los cuales pueden ser transmitidos sólamente en tiempos especificados, estando indicadas las variaciones de señal por las variaciones en la densidad de los impulsos.Improvements in, or related to, electrical impulse modulation communication systems characterized by an electrical impulse communication system in which the signals are invariably carried by impulses, which can only be transmitted at specified times, the signals being indicated. signal variations due to variations in pulse density.
