ABSTRACT:
A method for noise filtering and a noise filter are for the filtering of override signals in a numerical control system. If an input value change condition is present, an accumulator is reset and an input value is set as the new output value of noise filter. If a noise detection condition is present, the accumulator is reset while the output value is maintained.
