Chattering-free:
A circuit that can ignore the chattering phenomenon by using a filter circuit designed to
eliminate short signals under a certain length of time on the input of a switch signal is called a
“chattering-free input circuit.”
The operation of a push-button switch generates a phenomenon called “chattering.” This is
when an electrical signal occurs many times due to repeated electrical contact for very short
lengths of time when a switch is turned on or off. An operation to generate one signal ends up
generating multiple signals, causing errors when directly connected to an electric circuit. The
chattering-free input circuit prevents this kind of trouble.
