Abstract

Un montaje para engendrar oscilaciones moduladas en frecuencia caracterizado por dos fuentes de oscilaciones de frecuencia central alta y baja respectivamente en el cual una de las dos fuentes de oscilaciones es modulada en frecuencia al paso que la frecuencia de la otra fuente de oscilaciones es controlada en función de la de la primera fuente de oscilaciones por medio de un dispositivo de control de la frecuencia que es mandado por la salida de un paso de comparación de fase a cuya entrada son suministradas dos oscilaciones cuyas frecuencias dependen linealmente de las frecuencias de ambas fuentes de oscilaciones.An arrangement for generating frequency modulated oscillations characterized by two sources of oscillations of high and low center frequency respectively in which one of the two sources of oscillations is frequency modulated while the frequency of the other source of oscillations is controlled as a function from that of the first source of oscillations by means of a frequency control device that is controlled by the output of a phase comparison step to whose input two oscillations are supplied whose frequencies depend linearly on the frequencies of both sources of oscillations .
