摘　　要：m序列具有良好的伪随机性,可作为随机白噪声源,经过适当的带限滤波,可以得到带限高斯噪声。首先分析了高斯白噪声的特点,然后设计了利用FPGA产生带限高斯噪声的电路,经正交调制,送DAC输出,得到了较为理想的二维带限高斯噪声,最后对产生的噪声信号进行了测试。设计中始终考虑到节省FPGA资源,同时也达到了降低功耗、节约成本的目的。A band-limited Gauss noise is generated from an appropriately filtered m sequence which performs well on randomicity. At the beginning of the paper, the noise is presented briefly. Then a circuit is designed with FPGA and a well Gauss noise of two dimensions is produced and tested. Scale saving is taken into consMeration through the overall design, which conduces a lower power consumption.
