摘要
为改善高速数据采集系统的信噪比(SNR)和死区时间(dead-time),提出了一种将可变长度移位寄存器应用于高速数据采集系统的方案,给出了其FPGA的实现方法。仿真结果表明,该方案既提高了高速数据采集系统的信噪比又减小了系统的死区时间。
In order to improve the signal-to-noise ratio(SNR) and dead band time(dead-time) of high-speed data acquisition system,the method which a configurable shift register applies in the high speed data acquisition system is put forward and the FPGA implementation scheme is given.The simulation results show that the scheme improves the signal-to-noise ratio of the high speed data acquisition system,reduces the dead zone of the system time.
