In the differential signal detector manner and the device which detect the artefact making use of the homeomorphic mode signal

摘要

(57) Abstract The extent which is high, it is new manner in order to decide therefore whether or not, it deals with accurate diagnosis of the differential mode signal where this invention analyzes the compound input signal, the tonnage of the homeomorphic mode signal in the composite signal cannot allow is obstructed and something regarding the device. Step of the manner Claim here first, the differential mode signal which is dealt with is to separate the input signal into the intermediate signal which is known function of the homeomorphic mode signal (or those suitable combinations). Regarding one example of this invention, the intermediate signal correlating mutually, it generates those which display the correlation between the intermediate signals. Next that those which are displayed are compared with a certain threshold level. If comparison is desirable, it presumes the data, that it is not destroyed, analysis of the signal which displays the differential mode signal continues. Otherwise, that it is destroyed, it presumes the data, inhibits the analysis of the data. With the other example, the intermediate signal itself which displays the homeomorphic mode signal, first correlating with the intermediate signal which displays the differential mode signal mutually is compared with the dying and a certain threshold level. If this comparison is desirable, when possibility of deterioration is small, continues the analysis of the intermediate signal or the composite signal it can conclude.
