摘要: Abstract This paper describes a real time digital adaptive filter for processing myoelectric signals. The constant is automatically selected by the adaption algorithm, giving significant improvement over linear filters estimating muscle force and controlling prosthetic device. Interference from mains sources often produces problems processing, so 50 Hz all harmonic frequencies are reduced an averaging differential process. makes practical electrode placement contact less critical consuming. An economic implementation essential controller, this achieved using Intel 80C196KC microcontroller.
