    Abstract: Provided is a pulse noise suppression circuit. The pulse noise suppression circuit includes a filter circuit converting an input signal of a pulse type into an increasing or decreasing filter signal, a level reset circuit resetting the filter signal in response to the input signal and an output signal and an output circuit converting the filter signal into the output signal of a pulse type, wherein the level reset circuit resets the filter signal to have a high level when the input signal and the output signal all have a high level, and resets the filter signal to have a low level when the input signal and the output signal all have a low level.
