WebFeb 21, 2024 · Definition: The time required to change the output from one logic state to another logic state after input is applied, is called the propagation delay of logic circuit. It … WebThe propagation delay time for a gate is the time required for the output to respond to a change in an input. In all practical gates, a time lag exists between an input change and …
