PROBLEM TO BE SOLVED: To provide a time sequential signal analyzer capable of performing analysis only from cardiac sound signals. SOLUTION: By setting unit sections to time sequential signals such as the cardiac sound signals and obtaining the correlation of the time sequential signals and a plurality of periodic functions for each set prescribed unit section, a plurality of frequency elements are selected for each unit section. For each unit section, one integrated frequency element is calculated on the basis of the selected plurality of the frequency elements. On the basis of the array pattern of an integrated frequency element column for which the calculated integrated frequency elements are time sequentially arranged, block data for which the successive plurality of the integrated frequency elements are blocked are prepared. Attribute information is imparted to the prepared respective block data on the basis of a prescribed rule and the block data to which the attribute information is imparted are displayed. |
