| Abstract: | Total differential is taken for the combined signal, all the principal rings that form this combined signal are analysed. Real accuracy of all the rings is measured and finally the synthetical maximum error is obtained with the vector method. Based on the experiemental results the ways to raise measurement accuracy are indicated. |
