Abstract

Un sistema de difusion de audio digital incluye un transmisor RF y un receptor RF correspondiente. En el transmisor RF, una señal de audio digitalmente comprimida se codifica en una corriente de símbolos que primero se gira utilizando una frecuencia de 150,000 hertz (hz) antes de transmision al receptor RF.
