Abstract

Mejoras en sistemas demoduladores caracterizado por un desmodulador para sistema de impulsos con modulación en tiempo en el cual un impulso de señal varía desde una posición de tiempo determinada de acuerdo con su modulación que comprende una fuente de impulsos de gobierno medios para sincronizar el impulso de gobierno para que coincida sustancialmente en tiempo con el impulso de señal caracterizado por un circuito productor de impulsos que responde a la coincidencia del impulso de gobierno sincronizado y el impulso de señal para producir un impulso con un frente de ondas relativamente empinado medios de gobierno de corriente que responden al impulso de gobierno sincronizado para iniciar el flujo de corriente y que responden al impulso empinado para detener el flujo de corriente por lo que el impulso de salida resultante de los medios de gobierno de la corriente varía en duración de acuerdo con la modulación en tiempo del impulso de señal.Improvements in demodulator systems characterized by a demodulator for a pulse system with time modulation in which a signal pulse varies from a certain time position according to its modulation comprising a source of control pulses means to synchronize the control pulse to substantially coincide in time with the signal pulse characterized by a pulse producing circuit that responds to the coincidence of the synchronized steering pulse and the signal pulse to produce a pulse with a relatively steep wavefront current governing means that they respond to the synchronized steering impulse to start the current flow and they respond to the steep impulse to stop the current flow whereby the output impulse resulting from the current control means varies in duration according to the time modulation signal pulse.
