It's often using digital filtering method to eliminate the interfering signal presently, but this method is difficult to determine the frequency range of interfering signal, it can't distinguish interfering signal from real signal, and can't totally eliminate the distinguish signal on the condition of not affecting real signal. According that different segment of every cycle dynamic data has different...
A method based on digital filtering for studying the dynamic response of vehicles is applied to determine the rotation of vehicles passing over speed control humps. Design criteria for determining the optimal hump length which strongly affects the rotation, is proposed. The study focus on principal differences in angular response of buses and cars to explain the large and harmful acceleration recently...
An experiment was conducted to evaluate various methods for smoothing human motion data that has been subjected to noise during the filming and digitization process. Orthogonal accelerometers were attached to the subject's leg, and records of complex dynamic kicking motions were recorded on film and simultaneously sampled through an A/D converter on an IBM PC-AT. The filmed data was hand-digitized...
