A pulse is applied to each input of a 2 input NAND gate. One pulse goes HIGH at t = 0 and goes back low at t = 1 ms. The other pulse goes HIGH at t = 0 8 ms and goes back low at t = 3 ms. The output pulse can be described as follows

A. It goes LOW at t = 0 and back HIGH at t = 3 ms
B. It goes LOW at t = 0 8 ms and back HIGH at t = 3 ms
C. It goes LOW at t = 0 8 ms and back HIGH at t = 1 ms
D. It goes LOW at t = 0 8 ms and back LOW at t = 1 ms
Answer» D. It goes LOW at t = 0 8 ms and back LOW at t = 1 ms
