摘要： A device for removing a noise, in which a delay circuit is used for positively removing a noise contained in a signal regardless of the signal transitioning either from high to low or vice versa. The device includes a noise detecting part for comparing an input signal to a reference signal, to provide the reference signal if a pulse width of the input signal is smaller than a pulse width of the reference signal, and to provide the input signal if the pulse width of the input signal is greater than the pulse width of the reference signal. A noise removing part is also included for accounting and removing an output from the noise detecting part as a noise if the output from the noise detecting part is smaller than the pulse width of the reference signal and for determining and providing the output from the noise detecting part as a valid signal if the output from the noise detecting part is greater than the pulse width of the reference signal.
