PURPOSE: To prevent a user from feeling a sense of boredom by easily preparing a time sequential signal equipped with various fluctuation characteristics by changing a parameter value.
CONSTITUTION: The parameter value to be applied to an intermittent chaos preparation expression used by an intermittent chaos arithmetic part 16 is stored in a parameter storage part 12. The parameter of the parameter storage part 12 is selected by a parameter changing part 14, and applied to the intermittent chaos arithmetic part 16. The applied parameter value is substituted for the intermittent chaos preparation expression, and the time sequential signal equipped with the fluctuation characteristic corresponding to the parameter value is easily prepared by the intermittent chaos arithmetic part 16.
