An Analysis of Magnetic Shift Register Operation

The purpose of this paper is to describe quantitatively the design of a magnetic shift register. The article is divided into 3 sections as follows: A. A qualitative description of magnetic shift register operation. B. The design of a magnetic shift register. C. The effects of leakage inductance on stability and maximum speed of operation of a magnetic shift register. In section B, the equivalent impedance concept discussed in a previous article by the author is used in the quantitative analysis of a magnetic shift register. Optimum design conditions are derived and variations from optimum design discussed. In section C, the maxmum and minimum allowable values of leakage inductance are found such that the shift register remains stable and information is reliably transferred from core to core.
