Signal processing technology with the development of current science and technology level,has been integrated into all walks of life and people's daily life,and signal processing for operation of the equipment requirements are also rising,in the industrial control work also pay more attention to the sampling and analysis of signal spectrum.But the conventional spectrum analyzer cannot reach the requirements of data processing and analysis of some key signals,but also integrate deeper and more extensive processing procedures,so that the control level of spectrum analyzer in industrial production are changing with the flexibility level.In this paper,Fu Liye(FFT)algorithm and DSP chip as the main research object,at the same time on the basis of research and development in addition to the corresponding speech spectrum analysis system,the system in the current scope of conventional spectrum analysis which is very extensive.The system mainly includes two categories of client and server in function,the details include user login,communication function,user management,acquisition function,algorithm analysis function,data maintenance and so on.The basic steps in detail in this paper on the voice frequency analysis of time domain and frequency domain analysis system and its algorithm are introduced,and also pointed out the auxiliary facilities of the recognition system involved and their respective characteristics of the property,in addition to the system is designed to describe the characteristics and specific.In this paper,the spectrum analysis system is tested with scientific testing methods,and the test results are analyzed and tested in detail,which ensures the scientific and feasibility of the system to the greatest extent.
