Frequency Components of Signals Producing the Upper Bound of Absolute Error Generated by the Charge Output Accelerometers
The paper presents an assessment of frequency components by the time-frequency representation of signals with one constrain producing the upper bound of the absolute error generated by charge output accelerometers. The constraint concerns the amplitude resulting from the measuring range of an accelerometer. This assessment was carried out by using a wavelet analysis implemented in MATLAB. Mathematical basis regarding both modeling charge output accelerometers and determining the absolute error were presented. Shapes of signals producing the upper bound of error and results of analysis for selected parameters of the accelerometer model are also presented and discussed.
