| Summary: | 碩士 === 正修科技大學 === 機電工程研究所 === 96 === The digital signal processing (DSP) technology has been developed rapidly due to the widespread applications of high technology, the delicate division of labor, and the severe requirements for systems.
The DSP system has many good characteristics such as high degree of precision, high stability and agility, high integrated ability, and good interface. Nowadays, DSP chips have been widely applied in the developments of various equipments and apparatus.
This thesis uses a DSP chip, TMS320C5402, to develop an acoustic signal analyzing system. Numerical results show that by applying the DSP chip to retrieve acoustic signals, the functions of the developed system are becoming more and more completed.
The thesis has fulfill the following works: discussing the important meanings and recent progress of the acoustic signal measuring and analyzing system applying to industrial production, explaining basic principles of acoustic signal acquisition system, introducing the developed progress of the DSP system, theories of processing digital signals, and the steps of realization, describing the functions and characteristics of DSP chip, software development environment CCS(Code Computer Studio), depicting the characteristics and designing methods of TMS320C5402 chip which is the product of TI company, and utilizing the FFT technology to process signals on DSP.
