Abstract

Mejoras en circuitos de modulación por impulsos en tiempo que comprende: un circuito de entrada de señal para limitar la amplitud de señal; medios para producir un tren de impulsos similares sobre una onda electromagnética cada uno de dichos impulsos tiene un borde de inclinación; medios de retención doble para retener los impulsos a lo largo de sus bordes de inclinación de varias amplitudes determinadas por la salida procedente del circuito de entrada de señal para limitar el valor de desplazamiento en tiempo de las porciones de borde retenidas por los impulsos citados;y medios para diferenciar las porciones retenidas para producir impulsos modulados en tiempo correspondientes a los bordes de inclinación de dichas porciones.Improvements in pulse time modulation circuits comprising: a signal input circuit for limiting the signal amplitude; means for producing a train of similar pulses on an electromagnetic wave each of said pulses has a sloping edge; double latch means for holding pulses along their sloping edges of various amplitudes determined by the output from the signal input circuit to limit the time offset value of the edge portions held by said pulses; and means for differentiating the retained portions to produce time modulated pulses corresponding to the sloping edges of said portions.
