Abstract

Mejoras en radioreceptores para transformar en amplitud modulada de onda portadora en un equivalente bien de tiempos de impulsos modulados comprendiendo transformación de ondulaciones de la amplitud modulada de onda portadora en una onda trapezoidal de inclinación del lago del cual corresponde en substancial lineal proporción para la amplitud de las correspondientes ondulaciones, transformando las ondas trapezoidales en impulsos rectangulares las cuales varían en ancho de acuerdo con la inclinación de los correspondientes lados cortados de la onda trapezoidal y transformando dichos impulsos rectangulares cada uno al menos una estrecha anchura de impulsos correspondiente en desplazamiento al corte de un impulso rectangular.Improvements in radio receivers to transform the amplitude modulated carrier wave into a good equivalent of times of modulated pulses comprising transformation of undulations of the modulated amplitude of the carrier wave into a trapezoidal wave of tilt of the lake which corresponds in a substantial linear proportion to the amplitude of the corresponding undulations, transforming the trapezoidal waves into rectangular pulses which vary in width according to the inclination of the corresponding cut sides of the trapezoidal wave and transforming said rectangular pulses each at least a narrow pulse width corresponding to displacement to the cut of a rectangular impulse.
