- 摘要：
PROBLEM TO BE SOLVED: To provide method and apparatus for eliminating ham, adaptive, having real time property, and not exerting any influence on a bioelectric signal.
SOLUTION: A signal of only pure ham is directly obtained from a commercial alternating current power supply, shaped and then processed to be used as a reference signal related to a ham. The reference signal is processed so that the amplitude and phase of the ham in the reference signal agree with the amplitude and phase of a ham in a main input signal obtained by processing from a bioelectric signal where a ham gets mixed, and the processed reference signal is subtracted from the main input signal to eliminate a ham.
