At t=10, the inputs to AND gate are made 1. Now, for the electrical signals to pass to Y, it takes 20ns as per my knowledge. So, Y=1 would be available at t=30. 1 votes 1 votes Anusha Motamarri commented Nov 11, 2016 reply Follow Share gates take input at any point of time? or only at the end of each clock? 0 votes 0 votes Sushant Gokhale commented Nov 11, 2016 reply Follow Share At any point of time. And what is clock? It is an input signal, right? 0 votes 0 votes Please log in or register to add a comment.
1 votes 1 votes Intially A=0 B=0 At t=0 propagation delay of AND gate = 20ns and Intially Y =1 so At t=20ns then value of Y will become 0 from 1 . At t=10 A=1 B=1 and Y=0 so after 20 ns , At t=30ns value of Y =1 so at t=30 value of Y will change from 0 to 1 Amit Pal answered Nov 10, 2016 Amit Pal comment Share Follow See all 0 reply Please log in or register to add a comment.
