PROBLEM TO BE SOLVED: To provide a non-fixed oscillatory wave signal generating method and apparatus suitable for a patient undergoing electric therapy. SOLUTION: In a method of generating an oscillatory wave signal, a set of digitized time-domain basic wave signals are transformed into a corresponding set of frequency spectra. The set of frequency spectra are randomly processed, and are subsequently combined so as to obtain a mixed spectrum. The mixed spectrum is transformed into a time-domain synthesized wave signal corresponding to the mixed spectrum. Thereafter, the synthesized wave signal is converted into an analog wave signal. An apparatus for generating the oscillatory wave signal is also disclosed. COPYRIGHT: (C)2005,JPO&NCIPI
