Given that the guaranteed minimum propagation delay of a 7400 is 0ns and that its guaranteed maximum delay time is 20ns, and Z = AB + B'C, how long does it take the output Z to stabilize on the falling edge of B (in ns)? How long does it take on the rising edge (in ns)? Are there any potential glitches in the output, Z? If so, explain what makes these glitches occur. (lab 1)

a) 0ns; 20ns; Yes, due to the combinational logic involved
b) 10ns; 20ns; No, there are no glitches in the output
c) 0ns; 20ns; No, glitches are prevented by the logic gates used
d) 20ns; 0ns; Yes, due to the propagation delay
