Abstract
Device for determining an error induced by a high-pass filter in a signal, including a unit () for calculating the error according to the formula:()=()−()=·∫((α)−(α))()with: E(t) the value of the error induced by the high-pass filter, as a function of the time variable t, Πthe trigonometric constant, Fthe cutoff frequency of the high-pass filter, tthe initial instant, αintegration variable, Vthe signal input to the high-pass filter, Vthe signal output by the high-pass filter,the mean value of the signal V. A method of correcting the error induced is also presented and applicable to the error correction of a piezoelectric pressure sensor.
