The authors proposed a new method of pulse width modulator which can read out non-destructively by a square wave voltage of the comparatively low frequency (50 Hz). This modurator is constructed from the two-hole core which is made from laminating sheets of the Fe-Ni 50% permalloy with square loop properties.　This paper indicate a few points of the doubt in the modurator. Various hysteresis loops and B-H curves are drawn by means of Ballistic method. Moreover, many measurements give us the minor hysteresis loop behavior during partial flux reversal and the relation between leakage flux and number of readout in the operation for the modurator. From the experimental results, the memory holding characteiistics are discussed, and the propriety is estimated by the method adopted for the improvement.
