Abstract

Mejoras en radio receptores para la detección de señales con impulsos modulados en tiempo e impulsos impares de dicha energía que aparecen con una periodicidad dada, dichos receptores comprenden un dispositivo conformador de impulsos, un filtro que deja pasar sólamente las frecuencias del armónico productor de la expresada periodicidad y las inmediatas a él, y un dispositivo detector de amplitud.
