Real Time Implementation of a Tuning Device Using a Digital Signal Processor

Joseph Reagan, Sedig Agili and Aldo Morales E E/ E E T Programs Penn State University at Harrisburg Middletown, PA 17057


In this paper, an example of the use of a digital signal processing (DSP) board for teaching purposes and project implementation is demonstrated. Project implementation is carried out through the design of a guitar tuner using a digital signal processor (DSP) platform. The goal of the design is to optimize the DSP process so that the best results are obtained for the guitar tuner. This involves the proper selection of DSP parameters and use of DSP techniques to provide an accurate guitar tuning such as frequency resolution and sampling rates. The application was implemented in a target hardware system, the TMS320C5402 DSP Starter Kit (DSK). The program for the guitar tuner is written in the C programming language and makes use of DSP assembly functions provided by Texas Instruments. The program developed for the guitar tuner can be run in the Code Composer Studio (CCS) Integrated Development Environment (IDE) and is able to accurately tune a guitar in several common tunings. This project is interesting for the students to learn real time implementation issues of different DSP techniques.

I. Introduction

Penn State Harrisburg offers BS EE, BS EET, and ME degrees. The Bachelor of Science degree in Electrical Engineering provides an opportunity for students to pursue interests in electrical and electronic circuits, including digital circuits and VLSI and its fabrication, microprocessors and their applications, electromagnetics, communications, control systems, digital signal/image processing and computer vision. The BSEET program provides similar experience however, its strengths include: an applied, hands-on approach and extensive laboratory experience. Through a senior capstone design project, both curricula emphasize written as well as verbal communication and a teamwork approach among students to attain a common goal.

The Master in Electrical Engineering offers an education in the advanced aspects of modern electrical engineering. A candidate for the Master of Engineering in Electrical Engineering must write a scholarly report or engineering paper and defend it before three faculty members.
