| Abstract: | The technique of collecting electrical and electromagnetic fields mixed with EM noises by using HP3526A spectrum analyzer has been introduced in the paper. The technique has been applied for field measurements of noises in mines. Through field acquisition and spectral analyses of EM noises, the characteristics of the noisy signals could be studied, so providing a basis for developing a data acquisition technique of anti-interference EM survey. |
