Abstract

Un sistema demodulador para traducir a impulsos modulados en amplitud el desplazamiento en tiempo de impulsos modulados en tiempo desde una relación de control en tiempo dada de acuerdo con la amplitud instantánea de una señal de mensaje que comprenden medios que responden a los impulsos modulados en tiempo para producir una primera onda de una frecuencia que corresponde al promedio de tiempo de dichos impulsos, medios para dividir la frecuencia de dicha primera onda para producir una segunda onda de la cual la primera onda es un armónico par, medios para traducir dicha segunda onda a una tercera onda cuya frecuencia es un armónico impar d dicha segunda onda, un mezclador que tiene un nivel limitador de entrada, medios para alimentar los impulsos modulados en tiempo a dicho mezclador, y medios para alimentar dicha tercera onda a dicho mezclador con lo que la energía de dichos impulsos se combina con dicha onda para exceder dicho límite de entrada en valores de acuerdo con los valores y dirección del desplazamiento en tiempo de los impulsos.A demodulator system for translating into amplitude modulated pulses the time shift of time modulated pulses from a given time control ratio according to the instantaneous amplitude of a message signal comprising means responding to time modulated pulses to producing a first wave of a frequency corresponding to the time average of said pulses, means for dividing the frequency of said first wave to produce a second wave of which the first wave is an even harmonic, means for translating said second wave into a third wave whose frequency is an odd harmonic of said second wave, a mixer having an input limiting level, means for feeding the time-modulated pulses to said mixer, and means for feeding said third wave to said mixer with which the energy of said pulses is combined with said wave to exceed said input limit in values according to the values and direction of the impulse time displacement.
