With the advance of the computer control, the nondestructive read-out analog memory is of ever-increasing necessity as one of devices which combine the computer with the controlled system. The usefulness of ferroelectric elements and of various magnetic cores to form the memory function have already been suggested. Particularly, the multi-hole ferrite cores called the transfluxor excel others in performance and cost.　The authors used the multi-hole cores of laddic structure made of Fe-Ni 50% permalloy steel for realizing an analog memory. This paper describes fundamental experiments of the pulse width modulator which can read out nondestructively by the square wave voltage of comparatively low frequency, and describes the relation between the flux level and the flux path of each leg at the time of writting in and reading out.
