摘要：

AC magnetic flux density meters usually integrate a high pass filter with a very low cut-off frequency (1 Hz - 30 Hz) aiming at reducing the effect of slow oscillations. This can distort the actual time domain behaviour of induction waveforms detectable close to industrial or medical devices, even causing artefact high amplitude oscillations. This paper proposes a procedure to identify the filter parameters that accurately reproduce its measured frequency behaviour and suggests an algorithm to correct, in time domain, the field meter recorded waveform.
