Document Type and Number:
Japanese Patent JP2001343403
Kind Code:
A
Abstract:
To provide a signal processor for a Rogowskii coil, which eliminates the front end filter of an integrator by using an anti-aliasing filter constituted of a passive element to concurrently function as filter for inhibiting high fre quency level.
This apparatus is provided with the anti-aliasing filter, into which a signal from a Rogowskii coil is inputted and using a passive filter function for inhibiting high frequency level, an integration circuit constituted of an operation amplifier for integrating the output of the anti-aliasing filter and an A/D converter for A/D conversion of the output signal of the integration circuit.
