Abstract

Un sistema de comunicación por impulsos modulados en tiempo caracterizado porque se usan dos trenes de impulsos sólidos de igual frecuencia de repetición de impulso y desplazados en tiempo uno con respecto al otro, de modo que los bordes posteriores de los impulsos de un tren, coinciden con los bordes anteriores de los impulsos del otro tren y las ocurrencias de los bordes anteriores de dicho tren y los bordes posteriores de dicho otro tren, se modulan de acuerdo con la amplitud de la onda de señal en instantes de tiempo respectivamente diferentes.A time-modulated pulse communication system characterized in that two solid pulse trains of equal pulse repetition frequency are used and shifted in time with respect to each other, so that the trailing edges of the pulses in a train coincide with the leading edges of the pulses of the other train and the occurrences of the leading edges of said train and the trailing edges of said other train, are modulated according to the amplitude of the signal wave at respectively different times.
