Abstract

PURPOSE:To obtain a detection signal having a high S/N, by setting the time to apply a DC reproduction preceding the strobe pulse by a cycle of the rotary magnetic field frequency. CONSTITUTION:The induced noise has the repetitive characteristic and is synchronous with the rotary magnetic field. Making use of this fact, start of a DC reproduction is preceded the strobe pulse by a cycle. Thus the level of the nois preceding the strobe pulse by a cycle is exactly equal, and the induced noise is set at 0 at the time when the strobe pulse is applied. Thus the level of noise is assuredly suppressed by starting the DC reproduction preceding the strobe pulse by a cycle.
