Abstract

DISPOSICION DE CIRCUITO PARA GENERAR UNA SECUENCIA DE SEÑALES DIGITALES DE SALIDA QUE CORRESPONDE A VALORES MUESTREADOS DE UNA SEÑAL PERIODICA ANALOGICA TOMADOS EN INSTANTES ESPACIADOS UNIFORMEMENTE, SIENDO LA FRECUENCIA INSTANTANEA DE DICHA SEÑAL ANALOGICA MODULADA EN FRECUENCIA POR UNA SEÑAL DE CONTROL. CARACTERIZADA PORQUE UN ACUMULADOR OPERATIVO DIGITALMENTE, QUE COMPRENDE UNA PRIMERA UNIDAD ARITMETICA DIGITAL Y UN REGISTRO DE ALMACENAMIENTO, SUMA NUMEROS BINARIOS DERIVADOS DE LA SEÑAL DE CONTROL EN INSTANTES UNIFORMEMENTE ESPACIADOS EN UN MARGEN DE VALORES LIMITADOS; Y PORQUE LA SECUENCIA DE LAS SEÑALES DIGITALES DE SALIDA SE DERIVA DE LA SECUENCIA DE VALORES DIGITALES DEL REGISTRO DE ALMACENAMIENTO.
