Abstract

Los sistemas y métodos para proporcionar un mecanismo mediante el cual las señales digitales pueden convertirse a señales analógicas con una estructura eficiente que reduce el número de filtros requeridos proporcionando un mecanismo para cancelar las imágenes que se podrían generar. Ajustando tres parámetros en el sistema, se puede hacer una selección para generar ya sea bandas laterales superiores, bandas laterales inferiores, en cuyas direcciones la envolvente de la salida del sistema se desviará.
