SR Measurements have been carried out in this prefecture for the first time.

We implement a suitable acquisition system for Schumann resonance measurements.

Data logger detects the relatively weak signal in the presence of strong noise.

The 50 Hz peak is a very strong interference, but it is actually attenuated by the filters.

SNR improvement is about 22 dB.
