Patent ID: 8373056

Claim:
A waveform generation apparatus comprising: a Takens' plot processing means for expanding a coordinates information group to show original waveform data upon a two-dimensional phase space having a time axis and a wave height value axis to an n-dimensional phase space (n>2) including a time axis and a wave height value axis by using Takens' embedding theorem, and converting the coordinates information group consecutively to show an attractor data upon the n-dimensional phase space; an area demarcation means for demarcating a predetermined area upon the n-dimensional phase space; a time information acquisition means for acquiring the coordinates information group consecutively that belongs to a demarcated area, specifying one of the coordinates information from among the coordinates information group consecutively acquired and acquiring coordinate values corresponding to the time axis within the coordinates information as time information; and a waveform outputting means for, while outputting the original waveform data, generating and outputting a composite waveform data by adding a predetermined waveform data to the original waveform data from a position of the original waveform data upon the time axis corresponding to the acquired time information.
