Integrators using magnetic analog storage

This paper presents a few modifications of magnetic integrators which use a multiaperture ferromagnetic core (trans-fluxor) for storage. In such integrators a magnetic flux of a trans-fluxor control arm, caused by a negative feedback proportional to the rate of the flux change, varies as a function of an input voltage integral. After removal of the input signal, the value of the integral is remembered in terms of residual flux for unbound time. Readout of the magnetic flux in the transfluxor´s control arm is nondestructive. In the integrators discussed, it is possible to combine an integration function by adding several independent input signals. Input voltage ranges from 100 mkV 10V of any polarity. The total output voltage drift is not more than one percent of maximal operational output voltage regardless of the time.
