An '''ideal logic gate''' is a [[logic gate]] performing operations on boolean values in an abstraction - [[static power dissipation|dissipating no power]] and changing states [[propagation delay|instantaneously]], similar to a [[step function]]. Such gates operate on [[truth value|discrete logic inputs]] and ignore most physical characteristics such as [[gate delay|propegation delay]], maximum [[fan-out]], and various other electrical characteristics. Ideal logic gates are used in a wide variety of settings since it allows a person to make key observations about [[ideal logic circuit|a particular circuit]] without diving into the full specifications.
