一般的な説明

Glitch filtering is the process of removing unwanted pulses from a digital input signal that is usually high or low. Glitches frequently occur on lines carrying signals from sources such as RF receivers. Electrical or in some cases even mechanical interference can trigger an unwanted glitch pulse from the receiver.

This design outputs a ‘1’ only when the current and previous N samples are ‘1’, and a ‘0’ only when the current and previous N samples are ‘0’. Otherwise the output is unchanged from its current value.

For more details on glitch filtering please see application note AN60024.
