Design of Schumann resonance generator and detector

Schumann resonance is generated by lightning with a wavelength equal to the circumference of the earth. There is a practical need for Schumann resonance generator and the corresponding detector to fulfil relevant researches. In this article, we put forward a design of a flexible, reliable generator based on micro control unit and a high-precision detector based on digital signal processor. The parameters of the device are tested, which proves that both generator and detector are of superior performance and the set of device is well coordinated. The products are efficient, functional and very convenient to use, providing a helpful tool for further study of Schumann resonance.
