Resumen
Este proyecto de titulación tiene como propósito la implementación de un demodulador
digital M-ario16QAM en una placa de circuito impreso PCB el cual se pretende contribuir
a la mejora de la metodología de enseñanza practica dentro del laboratorio de
Networking/Telecomunicaciones de la carrera de teleinformática haciendo énfasis que en
la actualidad las transmisiones y recepciones digitales son muy importantes debido a su
gran porcentaje de eficacia. Por medio de esta investigación el estudiante se evitará de
comprar materiales y se concentrará solo en el estudio práctico y el análisis de los
componentes que se pusieron a prueba tales como el integrado AD633jn en la fase de
multiplicación de señal modulada con portadora, el efecto del uso de filtros pasa bajas en
la segunda etapa y el comportamiento del microcontrolador actuando como convertidor
analógico – digital para la recuperación de los 4 bits ingresados en la fase de modulación,
cabe destacar que se utilizó el programa Isis de proteous para la elaboración del diseño
electrónico y Ares para elaborar en pcb como esquema final para la impresión del
proyecto.
The purpose of this degree project is the implementation of an M-ario16QAM digital demodulator on a PCB printed circuit board which is intended to contribute to the improvement of the practical teaching methodology within the Networking / Telecommunications laboratory of the teleinformatics career by Emphasis that currently digital transmissions and receptions are very important due to their high percentage of efficiency. Through this research the student will avoid buying materials and will focus only on the practical study and analysis of the components that were tested such as the integrated AD633jn in the phase of carrier modulated signal multiplication, the effect of use of low pass filters in the second stage and the behavior of the microcontroller acting as an analog-digital converter for the recovery of the 4 bits entered in the modulation phase, it is worth mentioning that the Isis proteous program was used for the elaboration of the electronic design and Ares to elaborate in pcb as final scheme for the printing of the project.
