Research Of Multi-channel Signal Acquisition System

Multi-channel signal acquisition is a signal process,converting the collected multi-channel analog signal into data that computer can recognize,transmitting to the control system,and then get the proper signal that demanded after different calculation and processing according to different needs.The paper put forward a multi-channel signal acquisition system based on DSP and FPGA according to the signal acquisition module now existing and it increased the signal acquisition and processing ability to the maximum limit.PCI-GPIB interface card is used to connect computer and other instrument realizing the universality of the system.In the thesis,the structure of the multi-channel signal acquisition system is detailed introduced,also with the module implementation.The paper also gives verification and simulation for some software modules after the completion of the system hardware architecture.
