Each column and row winding of a magnetic storage matrix is connected to a respective Miller integrator, Fig. 2, comprising a transistor T, condenser C 1 and resistors R 1 and R 2 , the integrator producing read current pulses having linear growth and decay so as to reduce the amplitude of spurious outputs induced in the matrix sense winding. In Fig. 1 (not shown), resistor R 2 is connected to a negative potential through a selection switch, and the junction between the condenser and the transistor collector C is connected through a row or column winding of the matrix to a further negative potential. |
