Abstract

Un sistema eléctrico para la transmisión de señales en el cual la amplitud de oscilaciones amortiguadas sucesivas creadas en el transmisor o en el receptor son determinadas por las amplitudes en instantes sucesivos de una onda de señal de mensaje sonora o similar.An electrical system for signal transmission in which the amplitudes of successive damped oscillations created in the transmitter or receiver are determined by the amplitudes at successive instants of a sound message signal wave or the like.
