Abstract

SE MUESTRA UN APARATO PARA GENERAR UNA SEÑAL DE SALIDA EN REPUESTA A UNA SEÑAL DE ENTRADA QUE POSEE UN NIVEL DE ENTRADA VARIABLE. LA SEÑAL DE SALIDA POSEE UNA FRECUENCIA DE SALIDA QUE VARIA PARA REPRESENTAR VARIACIONES EN EL NIVEL DE ENTRADA. EL APARATO COMPRENDE UN CIRCUITO DE PROCESAMIENTO PARA EJECUTAR UN ALGORITMO DE PROCESAMIENTO DE SEÑAL DIGITAL PARA GENERAR SEÑALES DE CONTROL EN RESPUESTA A LA SEÑAL DE ENTRADA, CUYAS SEÑALES DE CONTROL SON REPRESENTATIVAS DEL NIVEL DE ENTRADA VARIABLE, Y CIRCUITO DE OSCILADOR PARA GENERAR LA SEÑAL DE SALIDA EN RESPUESTA A SEÑALES DE CONTROL. LAS SEÑALES DE CONTROL INCLUYEN UNA SEÑAL DE CONTROL PRIMERA QUE REPRESENTA UNA FRECUENCIA DE SALIDA PRIMERA, UNA SEÑAL DE CONTROL SEGUNDA QUE REPRESENTA UNA FRECUENCIA DE SALIDA SEGUNDA, Y AL MENOS UNA SEÑAL DE CONTROL INTERMEDIA QUE REPRESENTA FRECUENCIA DE SALIDA INTERMEDIA ENTRE LAS FRECUENCIAS DE SALIDA PRIMERA Y SEGUNDA. EL CIRCUITO DE PROCESAMIENTO GENERA AL MENOS UNA SEÑAL DE CONTROL INTERMEDIA SIEMPRE QUE LA SEÑAL DE SALIDA VARIE ENTRE LAS FRECUENCIAS DE SALIDA PRIMERA Y SEGUNDA QUE SIRVE PARA "SUAVIZAR" LA TRANSICION ENTRE LAS FRECUENCIAS DE SALIDA PRIMERA Y SEGUNDA Y REDUCE EL RUIDO QUE NORMALMENTE SE GENERA POR DICHOS CAMBIOS EN LA FRECUENCIA DE SALIDA.
