ABSTRACT:
A signal processing circuit for a magnetic bubble memory device is arranged to set a reference level for determining the level of "1" or "0" of the bubble sensing line signal during a period in which only a read signal corresponding to level "0" appears as the output signal of a differential amplifier of the bubble detector circuit.
