A Texas instruments DSP-based acoustic source direction finder

Abstract

This document describes the implementation of a DSP-based acoustic source direction finder and its application to control the direction of a steerable camera. For real-time implementation a TMS320F2812 digital signal controller was used. The system can be used for different applications like in teleconferencing rooms or surveillance systems. This report presents a description of the developed system in three phases of the project: direction of arrival estimation, analog interfase, and servomotor control. The application was developed by undergraduate students at the Autonomous University of Zacatecas as a final project in the course “DSPs programming”, which is one of the DSP courses thought in the Communications and Electronics Engineering program, with a major in DSP.
