Abstract

Mejoras en filtros de ondas eléctricas rotativos para la selección de una pluralidad de frecuencias distintas desde una fuente de energía oscilatoria que incluye cuando menos dicha pluralidad de frecuencias, comprendiendo para cada frecuencia a seleccionar desde dicha pluralidad medios almacenadores de energía que tienen porciones submúltiples, distintas medios para aplicar energía cíclicamente desde una fuente determinada a cada una de dichas porciones recurrentes de las ondas de las frecuencias respectivas a seleccionar y medios para obtener sucesivamente señales desde cada una de dichas porciones almacenadoras para cada una de dichas frecuencias seleccionadas, siendo dichas señales proporcionales a la energía almacenada en dichas porciones almacenadoras de energía y sincronismo con las respectivas frecuencias seleccionadas.Improvements in rotary electric wave filters for the selection of a plurality of different frequencies from an oscillatory energy source that includes at least said plurality of frequencies, comprising for each frequency to be selected from said plurality energy storage means having different, sub-multiple portions means for applying energy cyclically from a determined source to each of said recurring portions of the waves of the respective frequencies to be selected and means for successively obtaining signals from each of said storage portions for each of said selected frequencies, said signals being proportional to the energy stored in said energy storing portions and synchronism with the respective selected frequencies.
