Results of the experiments on resistor phantom. Column A to D is the four different scenarios with different disconnected electrodes. Row I shows the detailed location of the disconnected electrodes. ‘Infinite’ and ‘R’ respectively represent complete loss of contact and the high impedance resistor connection. Row II presents the corresponding EVC values of all electrodes. Row III is the EVC values ordered from small to large, which are prepared to be processed with DWT. Row IV is the final results of the reconstructed EVC sequence with level one detail coefficients. In Rows III and IV, the dashed lines mark the location corresponding to the reconstructed EVC minimum and abnormal values in the original sequence
