how do analog sticks avoid counting “snapping back” as an input?

Question

When you let go of an analog stick it snaps back to the center, how is this not counted as an input? Is this an hardware or a software thing?

Answer 1

Imagine holding the analog stick away from center as being like using a gas pedal in a car. The farther you push either, the higher the output for movement. Let go of the stick or the gas pedal and the output becomes “I no longer want motion.”
