This paper used the majority function to digitally filter back-electromotive force as an explanation of theBrushless DC MOTOR control algorithm. The cause and improvement of motor noise, which are operating in closeproximity to high frequency sources, did not use conventional low pass filter and comparator elements. Also, theyrepeatedly output a noise-free BEMF signal for the input value of the majority detection filtering. These filteringsteps can help reduce costs and minimize the area of a PCB by requiring relatively little hardware.
