摘要: According to an aspect of the present invention, there is provided a method detecting abnormal signal in compound sampled recorded time domain, comprising: dividing domain into plurality sample segments; transforming each segments from frequency determine transformed segments, segment having points, point amplitude associated with certain frequency; for given segment, determining ratio by value indicative average amplitudes points at same across repeating determination ratios segment; and using detect signal.
