Abstract

PURPOSE:To minimize the dispersion of the output waveform of the differential amplifier caused by the position of the core arrangement, by securing the uniform distances from the core to the both input terminals of the differential amplifier. CONSTITUTION:With selection of core 2 for reading, switch circuit 7 is turned off by control circuit 8. And the output signal of core 22 arrives at input terminals (a) and (b) of differential amplifier 4 with the same attenuation amount and the same delay time each. Thus the input waveform of amplifier 4 is changed into the bipolar signal of the symmetrical form, and the output waveform emerges in the form of the single-peak type waveform. On the other hand, with selection of core 3, circuit 7 is turned on and the low impedance is secured between points (c) and (d) of sense wire 1. As a result, the input waveform of amplifier 4 is turned to the bipolar signal of the asymmetrical form, but the difference is very slight. Accordingly, the output waveform of amplifier 4 is approximated to the single-peak type. Thus a large amount of margin can be secured.
