Portable Real-time Signal Analysis System

According to the short-comings of the system design in the dynamic signal analysis system domestic, this article designs a realtime signal analysis system basing on DSP component , FPGA component and PCI bus.Chapter 1 summarizes the development of the dynamic signal analysis technique and actuality in all over the world. And it also makes a introduction to the relative fields: the development of DSP component, Programmable Logic Device and PC interface bus .Chapter 2 sets forth the theory foundation of the realtime signal analysis system and brings forward a practical system design after comparing with the others design.Chapter 3 discusses the hardware of the whole system' design and the realization in detail. And it puts emphasis on the hardware desigin of realtime acquiring par, realtime processing part and realtime transferring part.Chapter 4 introduces the design of the processing software.And it puts emphasis on the design of FPGA and DSP, Compare with the two devices on realtime.Chapter 5 introduces the design of the realtime communication's programme, And it puts emphasis on the design of the USB programme.Chapter 6 summarizes the work above. According the trends of the relative fields it brings out the expectation of the dynamic signal analysis system.
