摘要：如何有效地压制各种电磁噪声，提高信噪比，保证大地电磁测深数据质量，始终是大地电磁资料采集与处理的核心问题。为寻求更好的处理效果，使用EMTF系统（单点，远参考以及多站同步MMT）对华北多个宽频MT测点数据进行了处理，并编写Matlab接口来方便地改写处理参数。与SSMT-2000对比，结果表明，EMTF系统在多数情况下可以压制噪声，并获得较好的处理效果，提高数据处理的效率。

英文摘要：

The problems as to how to suppress various kinds of disturbance efficiently, raise signal-to-noise ratio and guarantee the data quality have become the key issues in the collection and handling of MT data. To get more accurate resuhs, the authors introduced the EMTF system （single, reference and MMT） and used this system to process some of the MT data obtained from North China, and also compiled Matlab program so as to rewrite parameters easily. In comparison with SSMT-2000, the EMTF system can suppress the noise in most cases and greatly improve the efficiency of data processing.
