【摘要】 指出了用微积分电路进行加速度、速度与位移的相互转换存在的弊端和使用范围上的局限性，提出了一种新的转换方法，即采用FFT方法进行加速度、速度与位移相互转换的方法，实验证明该方法是行之有效的。更多还原

【Abstract】 The conversion between vibrational acceleration,velocity and displacement is usually per formed by using an integral differential circuit. This paper points out its defects and limitations and a new method based on fast Fourier transform is suggested. Experiment results show that the method is effective.更多还原
