Abstract :
For experiments in the circumstances of pulsed high magnetic fields, special measuring techniques are required. Usually in a pulsed high field, measurements have to be finished within the pulse duration (a few milliseconds). Meanwhile, the magnitude of the measured signals is small and the noise is large, a digital filter to deal with these signals is used. The purpose of this paper is to describe the effect of digital filter in the pulsed high magnetic experiments, as well as introduce the measurement environments of magnetization. In the end, a less deformation of signals is obtained by a designed filtering system with LabVIEW procedure.
