Methods and systems that use a simple hardware circuit and/or digital logic solution to identify and remove both positive and negative glitches from a signal. For this hardware circuit and/or digital logic solution, a glitch is referred to as an unwanted pulse with a width less than a specified duration, and is generally caused by noise or improper operation by other devices. A positive glitch occurs when the input signal has been logic low for some time, while a negative glitch occurs when the input signal has been logic high for some time. In one embodiment, the hardware circuit and/or digital logic solution removes noises from signals transmitted between a digital circuit and its switches and/or remote sensors, such as switches of keyboards and mice.
