PURPOSE:To detect a signal obtained from 10-20 data by digitizing plural data to be divided into plural sets, coordinate-transforming the same, and then adding data to the respective data lengths to be levelled. CONSTITUTION:From plural data, a special micro-signal included in the data is detected in the following steps. First of all, data is digitized. The i-th data is digitized and taken as Xi (t). In this case, (i) changes from 1 to m, and t changes from 1 to n. m is the number of data, and n is the length of digitized data. Secondary, Xi (t) is divided into L for each (i) of the digitized data. Xi (t) are arranged in the increasing order, and divided into L-sets by n/L each in the decreasing order to be put into the sections Di0-Di1-DiL-1-DiL. Subsequently, Xi (t) is converted into yi (t). yi (t) is added to each (i) for each fixed (t) to be levelled. When the obtained yi (t) is represented graphically concerning (t), the directing signal can be recognized. |
