Abstract

MODIFICACIONES EN EL METODO PARA CONVERTIR UNA PRIMERA SEÑAL MODULADA EN DELTA CON UNA PRIMERA FRECUENCIA DE BITS EN UNA SEGUNDA SEÑAL MODULADA EN DELTA CON UNA SEGUNDA FRECUENCIA DE BITS. CONSISTENTES EN: PROPORCIONAR LA SEÑAL DIFERENCIA ENTRE UNAS SEÑALES DIGITALES PRIMERA Y SEGUNDA, EN DONDE LA PRIMERA ES LA PRIMERA SEÑAL MODULADA EN DELTA, Y DONDE LA SEGUNDA ES LA SEGUNDA SEÑAL MODULADA EN DELTA; INTEGRAR LA SEÑAL DIFERENCIA PARA PROPORCIONAR UNA SEÑAL INTEGRADA; COMPARAR LA SEÑAL INTEGRADA CON UN NIVEL DE SEÑAL PREFIJADO; MUESTREAR Y ALMACENAR EL RESULTADO DE LA COMPARACION PARA PROPORCIONAR LA SEGUNDA SEÑAL MODULADA EN DELTA; QUE LA ETAPA INTEGRADORA ES REALIZADA DIGITAL O ANALOGICAMENTE.
