<p>Assuming usual gate design implementation of a Full Adder module, the propagation delay of an XOR gate is three times as that of an AND/OR gate. A 4-bit binary adder is to be made by using 4 such modules. The minimum propagation time of the entire 4-bit adder if the individual delay of an AND/OR gate being 2.4 microseconds is assuming no delay between modules?</p>
