Abstract
Mejoras en radio receptores para la recepción de impulsos modulados en tiempo que comprenden un circuito disparador oscilante ajustable para funcionamiento de intervalo normal a una frecuencia más baja que la frecuencia de repetición de impulsos no modulados de un suministro dado de impulso modulado en tiempo, medios controlados por las oscilaciones que ocurren en el circuito oscilante para cada intervalo de funcionamiento para producir un impulso de voltaje, medios para aplicar energía de dicho suministro de impulso a dicho circuito para sincronizar sincrónicamente el funcionamiento del mismo con lo que los impulsos producidos corresponden en ocurrencia a la ocurrencia de impulso de este suministro y medios para desmodular los impulsos.Improvements in radio receivers for the reception of time modulated pulses comprising an adjustable oscillating trigger circuit for normal interval operation at a frequency lower than the repetition frequency of unmodulated pulses of a given supply of time modulated pulse, controlled means by the oscillations that occur in the oscillating circuit for each operating interval to produce a voltage pulse, means for applying energy from said pulse supply to said circuit to synchronously synchronize the operation of the same with which the pulses produced correspond in occurrence to the occurrence of pulse from this supply and means for demodulating the pulses.
