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 results, 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.
