Abstract : The integrated response (velocity change) of an accelerometer signal was shown to be equal to the velocity change of the input pulse if the integration is carried out over a long period of time and the accelerometer response is finite. This was shown to be true even under conditions in which the accelerometer does not record the acceleration accurately. The derivation of the velocity change from undamped accelerometer recordings was shown to be simplified through the use of an electrical analog simulating a low frequency, highly damped single degree-of-freedom system.
