| Abstract: | A new random pulse signal acquisition system based on FPGA is described, including its hardware structure, working princi ple and system design . This system is different from the traditional data acquisition system , which acquires pulse signal by logic circuit in FPGA, independent of controller and software, It can work continuously in the whole time domain , taking no account of the memory over flow. Good characleristics such as high accuracy , efficiency, reliability and anti-jamming are incarnated in this system. |
