Abstract
A magnetic field measuring apparatus includes an A/D conversion unit, an integration unit, and a post-processing unit. The A/D conversion unit is configured to sample a signal at a predetermined sampling frequency and perform conversion into digital data, the signal being based on an output voltage from a superconducting quantum interference device configure to detect a magnetic field emanating from a living organism. The integration unit is configured to obtain a biological magnetic field signal based on a value obtained by integrating the digital data, the biological magnetic field signal indicating a magnetic field emanating from the living organism. The post-processing unit is configured to perform decimation processing on the biological magnetic field signal output from the integration unit.
