A DIGITAL INTEGRATOR FOR FAST AND ACCURATE MEASUREMENT OF MAGNETIC FLUX BY ROTATING COILS

摘要

A digital instrument for 10 ppm measurement of integrated voltage for magnetic field measurement by rotating coil was prototyped. A fully digital architecture based on a 18-bit ADC at 800 kS/s of sample rate, a DSP with a processing power of 400 MMACs, and a time-stamp resolution of 50 ns is exploited.
