| Abstract: | In this paper some advance on the error research in magnetotelluric data process are reviewed. Using the measured MT data, we discuss characters of the error distribution of MT response functions and the characters of the error propagation in its estimation; further expound the practically applied effect of the multi-channel coherent function method, modified by author, on the unbiased estimation and the diminution of the errors of the estimated values; and also discuss some problems on the synthetical error evaluation using several MT parameters. |
