What is the output of the NAND gate (Y) in the circuit below (Figure 1) when A and B are of the waveform as given in Figure 2. Take into consideration all the propagation delays (assume High-Low and Low-High transactions have the same delay). Show your answer by drawing the timing diagrams of W, X and Y. propagation delay TP1 - 3ns w S. 2 propagation delay TP3 = 2ns 3 B SI propagation delay TP2 = Ins Figure 1 Ons Sns 10ns 15ns 20ns B W Y Figure 2
