| 摘 要： | 由线性反馈移位寄存器产生出周期为ｐ＝２~（１１）－１的伪随机白噪声，利用快速傅里叶交换及其逆变换去除了其中低于３５０Ｈｚ和高于５５０Ｈｚ的分量，获得带宽在３５０～５５０Ｈｚ之间的伪随机信号

| Abstract: | White pseudo-random noise with period P=211-1 is generated by linear feedback shift registers. After components lower than 350 Hz and higher than 550 Hz in the whife noise being deldted by FFT and IFFT, pseudo-random signal with bandwidth between. 350 Hz and 550 Hz is obtained. |

| Keywords: | pseudo-random signal white noise fast Fourier transform single-chip microcomputer |
