Abstract

Mejoras en sistemas de comunicación múltiple caracterizado por el medio de producir un impulso que tenga porciones de diferente anchura, dispuestas verticalmente, y el medio de modular en tiempo con una señal el borde de ataque de cada una de dichas porciones y con otra señal el borde trasero de las mismas.Improvements in multiple communication systems characterized by the means of producing a pulse that has portions of different widths, arranged vertically, and the means of modulating in time with a signal the leading edge of each of said portions and with another signal the edge rear of them.
