DEVICE FOR DETERMINING AN ERROR INDUCED BY A HIGH-PASS FILTER AND ASSOCIATED ERROR CORRECTION METHOD

摘要

Device for determining an error induced by a high-pass filter in a signal, comprising a means (3) for calculating said error according to formula (I): with : E(t) the value of the error induced by the high-pass filter, as a function of the time variable t, ? the trigonometric constant, F<SUB>c</SUB> the cutoff frequency of the high-pass filter, t<SUB>0</SUB> the initial instant, a integration variable, V<SUB>e</SUB> the signal at the input of the high-pass filter, V<SUB>s</SUB> the signal at the output of the high-pass filter, V<SUP>-</SUP>
