Noise Acquisition & Processing System Based On PCI,USB

The data acquisition and processing system of underwater target radiate-noise is a high-speed multi-channel data acquisition and processing system.Its main task is to sample the underwater target radiate-noise signal and store the data to the disk.This thesis researches the design and implementation of underwater high-speed multi-channel data acquisition and processing system.There are some contents to be presented including designing a set of noise signal generator;design and implementation of underwater nosie high-speed multi-channel data acquisition and processing system;programming the Windows 2000 device driver cl PCI and USB with DDK2000;programming user interface of the control of the acquisition and display of the image with VC++6.0 .This thesis aims at hardware and software design of the system.During the hardware design,I think mostly over high-speed and stability of data transfering.and for the software design,I consider how to cooperate with the hardware design.The whole system has been verified in experiment on the Song Hua lake in September this year.
