【摘要】 介绍了一种微机测控系统中用来测量正弦信号有效值的方法,能够在较低的采样频率条件下得到高精度的测量结果。通过对一组正弦信号在不同采样频率时的测量结果,证明了该方法的有效性。该方法已被成功地用于振动传感器的校准系统中。更多还原

【Abstract】 A kind of method is described in this paper that is used to measure the RMS of sine signal with high precision in observing and controlling system based on computer. Depending on this method, the high precision results can be obtained with lower sampling frequency. The method proves to be effective through the analyzing of a set signals at different sampling rate. This method has already been used in the calibrate system of vibration sensors.更多还原
