Detailed explanation-1: -Propagation delay time: Propagation delay is the time required for a digital signal to travel from the input(s) of a logic gate to the output or the delay it takes to change the state.
Detailed explanation-2: -Explanation: The time required for a gate or inverter to change its state is called propagation time.
Detailed explanation-3: -The time taken for the circuit to change from one steady state to another steady state is called the transient time.
Detailed explanation-4: -It is important because it defines the minimum time it takes to ensure a valid output result before the result can be used and therefore based on the depth of logic levels how fast the logic can operate. Gate delay is the length of time taken for the quantity of interest to reach its destination.
Detailed explanation-5: -NAND and NOR gates are universal gates.
